I hope they can fix your cat :o The first cat we lost was Bono, he had a seizure and he tried to move around whil dragging his legs, it was heartbreaking to see and we had to put him down, and his brother eventually died in his sleep because he got very lonely without Bono, his name was Rodie by the way :x And i had a hamster called Hammie, he died at the age of 5 o_o I loved that hamster!
I wish you good luck with your cat, and i know what its like to have close calls with family, well in some cases for me they were more then close calls, but i just wanted you to know that i understand, i'll shut up now :x *waves*
