My thanks to the experienced member of the forum who suggested I start a new thread on this problem after my initial post this morning . I have a five week old kitten who was in a litter that was rescued. My daughter has taken her to the vet and had her exrayed and there seems to be no obvious reason why the kitten has no use of her back legs. Her little back feet are limp. She can "sit" up and she pulls herself forward by her front legs. The vet calls it neurological and has no suggestions. Does anyone have any input on this? I am feeling very sad over this little kitten.
