Rats are very clean animals and therefore their cages should be kept very clean. Your rat will not be happy living in a dirty cage. Cages should be cleaned every 3 days and waste matter should be removed daily. You should have a small pet carrier on hand to put your rat in while you clean out the cage. These carriers can ... be used when taking your rat to the vet, or where ever else you decide to take them.

Rats and mice are rodents belonging to the gnawing family. Their teeth grow continuously throughout their life and, therefore, the animal must constantly keep them worn down by chewing on things. Because of this, rats should not be left to run loose in the house as they can chew on things such as electrical cords, furniture, bedding, etc.

Rats are very soft and warm, and look just like a plump puppy. Adult rats (about six months) are a good sized animal to handle. They're not too big like a dog, but not too small like a mouse.

Kangaroo Rats are unique in the animal world because nature has provided them with the ability to survive with very little water and, in the deserts, with no free water at all. They do not store water in their bodies for future use like other animals, yet experiments have shown that their bodies have about the same water content as other animals.

Rats are very clean animals. They are constantly grooming themselves (like cats), so no additional grooming is required on the owners part. If you house more than one rat together they will groom each other.

In the first study, Proneuron's implanted macrophage technology restored movement in rats with severed spinal cords. Macrophages were stimulated outside the body by exposure to segments of regenerating peripheral nerves and then implanted in the severed spinal cords of 22 rats. Three control groups of rats did not receive treatment. Motor function in the rats' hind limbs was assessed for 16-19 weeks. Beginning two weeks after injury, 70% of treated animals (15 of 22) showed significant recovery of motor and behavioral activity, including vigorous voluntary movement in the hind limbs equivalent to approximately 40% of normal voluntary movement. No control animals showed any recovery.
