Hello,
There is no way I can give honest and credible advice without advocating that this cat sees a vet asap. There are non profits that can provide financial assistance and some that even have a vet on staff to provide care. This cat needs an examination and some diagnostics.
Please call your local vets, shelters and rescue groups. Look for help on every local social media platform and keep asking for help. Start a go fund me. The best advice I can give if this.
We need more information to help you and your cat.
Please stay tuned. I am working on this very topic
Hello,
If the limping doesn’t resolve with rest and there is swelling then I think that you need an Xray.
