My Cat Koda is about 13 months old, My (Army) unit went to the field for 2 and and a half weeks my husband stayed home. When I got back yesterday I noticed something was wrong with Koda's back legs. I didn't notice right away because his does not appear to be in any kind of distress at all. The only reason I did notice was because all three of my cats will come running to me if I kneel on the floor and snap my fingers because that usally means they are getting some kind of treat or lots of pets and Koda didn't come at first and when he did he came over to me and sat down in front of me I noticed he sat down kind of funny. So I checked him over and the only thing I could find wrong with him was he had runny eyes which both my Somalis get from time to time. I felt his back legs over and he didn't at any point seemed bothered that I was touching his legs. He dosen't seem to be in any pain I took out my 'da bird' to see if he would play with it and he tried to play with it like he always does but he seemed to have alot of weakness in his back legs. He walks normally like he always has but he doesn't run, he sits alot, and he can't jump up and jumping down off of our bean bag he fell over when he hit the ground. Does anyone know what the problem could be. I would have rushed him to the vet but there is no emergancy vet I can go to and I have to wait until monday to even call our base's vet.
