I've been known to soak a cat's foot in Epsom salts. How is it doing today?
I'm so happy I could help! Yes, it is a good thing that it is draining. An abscess is just a pocket of puss similar to a pimple (inflammation signaling cells, debris and water that result from the cat's body fighting the infection). Please try to get your cat to a vet as soon as possible so they can properly apply antibiotics to prevent the abscess from resurfacing. I hope you and cat are doing well!
Thanks I'll check it out. Its starting to drain, good thing I guess?
I found some helpful websites that you could apply for the day until your cat can see a vet. I hope this helps!
