Attention
Rat Lovers! NOTE: The information on this page is more up-to-date than the PDF files. I will remove this message when both are the same. Thank you.
Rats make excellent pets! They are clean, extremely smart, and very social toward humans, making them one of the best pocket pets out there. Of course, they are often greatly misunderstood -- many people continue to associate them with the kind of rats you'd find in a city sewer. However, domesticated rats are as different from wild rats as labrador retrievers are from wolves! Jack Hanna says that rats are the nearest thing to a dog you'll find in a small mammal! Times are changing, and rats are becoming very popular as household pets. Sadly, compared to other companion animals, there is still not a whole lot of information out there on rats as pets -- accurate or otherwise. Hopefully, this brochure will help you learn the basics of proper care for these wonderful little rodents. I also hope to help you find the perfect supplies and accessories to give your rats the best possible life. I have used many of these products myself, and highly recommend them. Though greatly abbreviated, the information contained in here should help anyone get started, and point you in the right direction to find the facts you need. I highly recommend seeking out the items on the Suggested Reading list at the end to learn more.
Rats should always be kept as pets in same-sex groups of two or more, for many reasons. In the wild, rats live in immense colonies, and naturally need and enjoy the company of other rats. They groom each other, sleep together and play together. No amount of human attention can replace the company of another rat. Therefore, pet rats are better off with at least one other for companionship. It is also believed that pet rats fare better emotionally when kept in groups, which not only keeps them happy, but healthy, too! Single rats often seem to be more easily stressed and can be more prone to disease -- some rats can even develop behavioral problems or neurotic tendencies when kept alone. Since caring for two rats is no more difficult than caring for one, and the extra cost is nominal compared to the benefits of having two together, there really is no reason not to get two or more. As long as you give them attention individually, they will each bond with you -- in fact, many people believe that keeping two rats actually helps them bond to you more easily. Though it is very possible to introduce a new rat as a companion for a single rat, it is much easier to get both at the same time, preferably from the same litter, as they have grown up together and already know each other. Debbie Ducommun has written an excellent article about introducing rats, which is available on The Rat Fan Club Web site, under Helpful Info, at www.ratfanclub.org. I have used this article to introduce my own rats, with great success.
Rats are very social animals, and are most easily socialized with humans when they are young. Therefore, it is important in their social development to have contact with humans from almost the moment they are born. Not only should breeders and pet store employees handle or interact with the rats at least once a day, they should also allow you to have direct contact when visiting. In many cases, the best way to choose a pet rat is to allow the rat to pick you! The most social rats make the best pets of all. Just be sure that your hands are clean -- the rats may detect food scents and try to bite (thinking it is a morsel, not to be mean), or may smell another animal and become very frightened. Most human illnesses are not transmitted to rats (strep throat is one exception), but itŐs better to be safe than sorry. If you are ill, avoid the pet store or breeder until you are feeling better. HOW
TO PICK UP A RAT
Husbandry
The environment pet rats live in is very important. Rats have a few special needs compared to some other pocket pets, such as hamsters or gerbils, but they are easily accommodated with a little knowledge and common sense. CAGES
Wire cages (such as rabbit and ferret cages) are by far preferred. They offer superior ventilation, plenty of climbing opportunities, and better flexibility for modification and "decorating." Space between wires should be between 1/2" x 1/2" (for babies) and 1" x 2" for adults. Some good cage manufacturers include:
Some
people believe that wire-floored cages need to be covered to protect
rat feet from developing a condition known as bumblefoot (ulcerative
pododermatitis). This is not actually true. Bumblefoot is actually
caused by a number of factors, including genetics, body weight, improper
pressure, and cage cleanliness. I recommend a variety of surfaces
for them to walk on. In my cage, I only have one level covered with
vinyl carpet runner. The ramps and balconies are left uncovered. BEDDING
Keep in mind, also, that clumping and clay-based kitty litters are not advised. Clay-based litters are very dusty, and can cause problems with the rat's delicate respiratory system. Clumping litters can cause problems if ingested. It's important to remember that cats only visit their litter box to do their business. Rats live in their litter. Paper-based cat litters are fine, and a few of them are included in the list below.
CLEANING
Though cages can be cleaned with a commercial pet cage cleaner, sometimes the fumes from these types of products can cause respiratory problems. It is recommended to clean the cage with warm water and a mild soap, rinsing thoroughly. A very diluted bleach solution is also acceptable. Household cleaners, such as Windex, Fantastik, etc., should never be used due to harmful fumes. ACCESSORIES
AND TOYS Some rats enjoy exercise wheels, but usually only the females, and only if they have been exposed to a wheel at a young age. I personally have yet to get one of my boys to use a wheel, but all rats are different. Of course, since a rat is bigger than a mouse, hamster or gerbil, they need a bigger wheel. Wodent Wheels are made especially for rats, and come in multiple sizes, depending on the size of the rat. Wodent Wheels are manufactured by Transoniq. Transoniq
Another accessory that really should be a must for all rat owners is a carrier for transportation to the vet. I have taken my rats to the vet in cardboard boxes, plastic terrariums and glass aquariums, but nothing beats my Cabin Kennel. Similar to a cat carrier, a Cabin Kennel is specifically designed for pocket pets like rats, ferrets and chinchillas. The Cabin Kennel is also airline approved, should the need arise to bring your pet on a plane trip. Cabin Kennels are made by Doskocil. Doskocil
One more accessory a pet owner might consider is a Pet Corral, which can provide a safe playspace, and not ruin any furniture. Pet Corral, and the larger version, the Grrreat Wall, are manufatured by Milestone Innovative Products. I have a Grrreat Wall, and I love it! Milestone

STAPLE
DIET The best nutrition for rats is in the form of a Lab Block. It has all of the daily requirements a rat needs. Some of the best brands are listed below. Be sure to choose a block that does not have corn as its first ingredient; soy- or wheat-based blocks are preferred. I have been using Owxbow's Rodent Maintenance Formula lately, which seems to go over very well -- much better than most lab blocks. It contains no corn, and has the same protein content of Nutro Natural Choice Lite. Note to pet owners: not all the brands listed below are available to purchase from the manufacturer. Where possible, I have listed a retail source for the listed products. Otherwise, contact your local shops and ask if they carry any of these:

Purina Mills

lab blocks available via retail:
Kaytee FortiDiet for Rats & Mice Some dog kibble is fine for babies and nursing mothers, as it helps the babies grow, and helps mom retain her strength while nursing. I have also found that adults do just as well on light dog foods (for senior or overweight dogs). The best dog food brand for rats that I have found is Nutro's Natural Choice Lite, which has low protein (14%) and is lamb- and rice-based (not corn). In general, the protein content of a rat's diet should not exceed 25%. Below 18% is best for adult males. Some rats are more sensitive to protein than others. Seed mixes formulated for rats and parrots are fine as a supplement to the staple diet, but should not be the sole diet. These mixes often contain items that go to waste, such as alfalfa pellets and tiny seeds. They also do not provide complete nutrition, and contain a lot of seeds and nuts that are high in fat, which can cause obesity and protein problems (where the rat will become itchy, and scabs will develop). If you would like to know what I feed my own rats, feel free to take a look at my recipe at www.ratsrule.com/diet.html. I feed them a combination of Nutro's Natural Choice Lite dog food, Oxbow Maintenance (when available) and a homemade grain mix. Debbie Ducommun also has a complete homemade diet featured on the Rat Fan Club web site which offers balanced nutrition. The RMCA also has its own homemade diet. WATER
In the summer, two or more bottles should be maintained, if possible. Store unused, full bottles in the refrigerator, and switch them throughout the day. Rats can only release excess body heat through their tails, so they can become overheated fairly quickly. If a rat does happen to go into heatstroke, he can be given an electrolyte drink like Pedialyte to help recover. You can also immerse him in lukewarm water, and promptly dry him with a towel. TREATS
Small items -- such as Rice Krispies, Cheerios and rolled oats -- make excellent training aids. Rats love them, and they are small enough to eat quickly. In addition, the animal will not get full too quickly, so training sessions can last longer. One product that offers acceptable commercial treats is Vitakraft. Two products of theirs that are very popular with rats are the yogurt drops (any flavor) and the Cheese Wedges.
Vitakraft Pet Products Co. Another manufacturer of yogurt drops is Eight In 0ne. They make Yogies, which are available in a variety of flavors. My boys prefer peanut butter and cranberry, which are marketed as ferret treats. Why they don't make "rat" flavors is beyond me. Eight

I don't have enough room to cover every medical condition rats can face, but there are two major concerns that one should watch for -- respiratory problems and parasites. I'm going to cover a few of the major symptoms to look out for, and make suggestions of what you can do. I am not a vet or an expert on rat health care, but I have had first-hand experience with these conditions, and have conversed with both my veterinarian and an internationally-recognized lay-expert on rat health, Debbie Ducommun. A good source for more in-depth information about rat health is her book, Rat Health Care. More information about this valuable resource is listed in the Suggested Reading section. As always, consult a veterinarian in all medical matters when it comes to your pets. RESPIRATORY
PROBLEMS
Wheezing or noises while breathing Advanced
symptoms may include: If your rat exhibits any of these symptoms, it should be treated with antibiotics from a vet. Observe the other animals in the cage for similar symptoms -- secondary infections are often contagious. It is often advisable to treat all of your rats at the same time. A
WORD ABOUT ECHINACEA EXTERNAL
PARASITES
Excessive itching The best treatment for parasites is a visit to the vet for an ivermectin prescription. Though ivermectin can be injected, it is easy to overdose. An accidental overdose can be fatal. I prefer to apply the injectable liquid topically; just a drop between their ears, which they will groom and ingest. Another ivermectin alternative is an oral dose of a horse wormer that goes by the names Equimectrin or Zimectrin. Dosage is a blob about the size of an uncooked grain of rice, once a week for two to three weeks. This can be tricky, as the horse wormer is often not evenly mixed, so a vet check is preferred. Flea powders should never be used, as they are far too dusty, and can irritate a rat's delicate respiratory system. Shampoos will only kill the adults, and does not stay in the system long enough to affect the eggs as they hatch.
Female rats should not be bred from until they are at least three months old. There should be a space of at least two months between litters (starting after the last litter is weaned), to allow the mother to regain her strength after bearing and nursing a litter. Lastly, each female should not be bred more than two or three times in her lifetime. A female comes to the end of her breeding cycle at about 18 months of age, so it is not a good idea to breed her after that time. Litter sizes will decrease as her fertility wanes, and there could be complications. Breeding,
however, is not something to be taken lightly, by any means. Breeding
any animal responsibly means making an effort to improve the species
as a whole, not just to make more animals. This particularly applies
to rats. If you are considering breeding, it is important to know rat
genetics, have a breeding goal that involves improving the species,
mentoring with a reputable breeder, and starting with good breeding
stock from a reputable breeder. Pet store rats are NOT breeding material.
You need to know the health and temperament history of your rat's line,
going back several generations, including extended family, before you
think about breeding him or her. Breeding is a monumental responsibility,
and requires a lot of dedication and hard thinking before you begin.
Blue Velvet Rattery has a very good article entitled, "Should
I Breed My Rats?"
When baby rats are a mere five weeks old, they are ready to reproduce. Therefore, males should be separated from the litter as soon as they are weaned from the mother (about five weeks of age), and should be kept separated from the females at all times. This will prevent the accidental pregnancies (which seems to occur at an alarming rate in pet shops). Many of these young rats are far too young and underdeveloped to healthily support an unborn litter, as they are not yet full-grown themselves. Likewise, the mother is far too weak to support an unborn litter so soon after weaning the previous litter, should one of her sons get her pregnant. Separating a litter by gender after weaning is in the best interest of the health of these young rats and their mother. Once rats reach 3 weeks of age, it should be pretty obvious which are male and which are female (though it can be determined sooner, with experience). The males' testicles will be visible -- though they can pull them inside at will, especially if they are nervous or frightened. Females should have visible nipples on their bellies. The best thing to do is compare a few until you find two that are different, and then it will be easy to tell who is what. The diagram below should help.
