Have a cat only 3 years old! It could never jump real good! Last
week, I came out to its outside pen and found it sitting on the
ground! The Vet said the joints on its rear legs pop out!

Could be Patellar Luxation -- the kneecap pops out of the groove it rides in
and gets stuck on one side. There are 4 grades of severity. Did your vet
grade the luxation?

The Vet
gave me some pain medicine and said the cat probably had overdone it!
The cat has good days and bad days! Seems not to be related to pain
medicine! The Vet said I could go to a specialist! Anyone out there
have any experience with this?

Gotta get it fixed. Later in life the degenerative changes caused by the
patellar luxation will precipitate into lameness.
