Cat Paw

At first I thought my cat hurt his leg I'm beginning to think it's a skin thing. The fingers are seasons?
At first I thought my cat injured his leg now I'm starting to think it is a thing of skin. The toes are beginning to swell, spread and are red. The bottom of your foot seems irritated, and cut almost. Does anyone know what this could be? We have not changed food or garbage. She is only an indoor cat, so it is very unlikely it was a bee. She does not act as if it were injured, making it the only reason I hesitated to take her to the vet. Is there a way for me to add photos? I took a couple of pictures of her. He was also declawed years ago before I had it.
It could be an allergic reaction to something he did a step in. But it can be a bit earlier or cut is infected. You could try soaking it in Epsom salt, but I think it's a trip to the vet.
