Thanks for your help everyone. Stitch is doing better, but I think she may have arthritis. It just started getting cool here in North Florida and that is when she started showing these symptoms. She still limps a little bit and has some lameness in her left leg, but it seems to be better. Her crate is a good size- not too big, not too small. She can stand up and turn around in it. I have a water bottle attached to the side for her. She will crawl into her crate at night when everyone is in the living room watching t.v. (her crate is between the LR and DR), so she really likes the crate. I am going to take her to the vet next week before I go out of town to have her checked for arthritis. I heard that it is easily treatable- just like in humans. I hope that is all it is..
