I am guessing he hurt himself Debby. First off, you need to understand that he's a bit of a drama queen, so when he yelps, you never really know how bad (or not) it is! LOL! He seemed OK yesterday morning when he got up, but not far into the day, he seemed off. They he started to yelp when we would try to pick him up or move him. He ate his morning treat...I give them a small piece of Rollover (a tiny little cube, probably smaller than a dice) as a treat after their first bathroom break in the morning and last one at night. But, he never ate his dry food. I usually feed 2 portions of it a day, but never ate the first, so I never gave any more for his afternoon mean. He did eat leftovers from supper, but never ate his dry. He usually eats all of his meals, and then even asks for more in the evening. He never did last night. He seems like he may be sore in the shoulders or something. I got to thinking, and remembered that Sunday night, I was throwing his toy up into the air for him. He was on the large ottoman thing, and when he jumped up, and went to land, he toppled to the floor between the couch and the ottoman. I was speaking to my daughter on the phone at that time, and that is why I remembered it today, as I was telling her about it, then suddenly remembered that. At the time, I laughed at him, and he never yelped, or seemed sore or limping or hurt in any way...just kept playing. But now after his being sore early in the day, I think he must have hurt himself from the fall. Maybe jarred his shoulder or even his spine. I don't feel it is anything serious, requiring a vet visit, as upon palpation, he seems "ok". So, I am just hoping that the aspirin will help my little dram queen with any pain and inflammation he may be experiencing. And yes, he is absolutely the apple of my eye, so if I even remotely thought it was something worse, we'd be at the vet.
