My one cat was stung by a wasp and ended up with a very swollen leg. I suppose each animal will react differently. The vet gave him an injection to reduce the fluid build up and sent him home. I would keep an eye on him for sure, but would wait it out. It seems to be pretty darn common. I hope other people chime in with some advice, soon, cause I am not sure I know what to tell you other than "the above"...

Keep us posted about sweet Kia with the pretty blue eyes!
