My little guy is almost 7. Out of the blue late last night he had sudden trouble with his hind legs which I noticed when he went to the bathroom. By the time he went to bed about 30 minutes later, he could barely stand up or move his legs and he was clearly not comfortable. His hind legs basically gave out. It was frightening, but thankfully this morning he is able to stand and walk (a little slower than normal), and he’s been sleeping all day. I’m going to limit his walking/jumping and take him to the vet in a few days, but what wondering if anyone has had a similar experience.
