My cat is having a hard time walking around. He seems very off balance and struggles to walk straight and is not able to jump up anywhere easily. I have taken him to the vet and when blood tests were done the blood clotted right away so he said it was an infection. My cat was put on an IV with an antibiotic and stayed the night with the vet. The next day he seemed somewhat better but still was having a hard time walking around and looked very off balance. My cat was put on antibiotics for 8 days and that has not seemed to help with him walking right. Any ideas what this may be for when I bring him to the vet? Thanks for your help!
