Hi, I can help you with your question today.
Yes, cats can definitely develop arthritis.
I think you are on the right track too. It tends to be worse when an animal gets up from rest, and slowly works out.
It might be a good idea to have her evaluated by your regular vet to confirm this.
They can do a physical exam and x-ray of her shoulder.
Aside from that, there are some things that we can do to keep her more comfortable.
You can purchase a joint supplement like Cosequin. This may be enough to keep her comfortable.
I also recommend starting some pain medication for her.
For cats, we are limited in the choices available.
I like to use buprenorphine or Onsior.
If her pain is significant, we can actually use all three together: Cosequin, buprenorphine and Onsior.
Once she looks more comfortable with the medications, we can try to reduce the frequency of each one.
I would keep her on the Cosequin daily, but we can try to give the Onsior every other day instead of daily.
The buprenorphine can be given as often as every 6 hours. I would probably start her at twice daily, then discontinue if possible.
We will need to make each change and then monitor her response for several days. If she begins to appear uncomfortable again, we will have to bring the dose back up.
