If you aren't petting her will she wadles around she starts going in a cirle acting like shes blind..I have had this new rat for a month and she is going thriugh the exact same thing..i can't tell for shure if shes blind...does she maybe have a tumor..Please help!!

Answer
 When a rat drags its back legs it usually is caused by a spinal injury, brain tumor, head injury, or other neurological disorder.  Most rats with such an affliction are euthanized due to a poor quality of life.

 If your new rat is doing this it certainly is cause for alarm.  Circling can be a result of neurological problems or even something as simple as an inner ear infection.  Either way, a visit to the vet is definitely in order.  Your vet will be able to have a better idea of the cause of the problem and will let you know whether or not it can be treated.  I hope everything turns out well for her, good luck!
