I think it is hilarious how most replies that deal with animal injuries just inform the owner to take the animal to the vet. If u have no more useful information to give then what ne pet owners last resort n probably first thought was, just stop wasting everyone's, (including your) time, geez-u think it would b a no brainier to just not post if u have no valuable info to write! Cats and dogs for that matter r more resilient then peps give them credit for. Cats have been around since 1600 bc, or that's at least the first documented ownership of a domestic cat and the first vet wasn't till the 1700s and better yet the first school wasn't until almost the 1800s! Cats prospered and lived hundreds of thousands of years without vets and still could today. There are some serious conditions that need treatment but there is tons of money wasted every year on vet visits that were unneeded! And as for treating your kids the same as your pets, that freaking ridiculous! I grew up on a farm, have two kids and 5 pets currently. I love all my animals n believe when u take on a pet it's a responsibility n ur job to care for its needs but in no way would compare that to love or the distance I would go for my child. Neone who puts its pet on the same level as its child should note allowed to reproduce. If my dog bit someone and seriously injuries them for no reason (wasn't teased, hit, etc...), I would definitely have to consider having it put down or caged unless supervised. If my child bit someone, none of these same thoughts would even enter my mind! Oh n as for the answer, "what would u do if your child's hand was slammed in the door?"-I guess it would all depend on the severity of the injury. Went camping 3 wks ago, n my nephew actually shut door completely on his index finger. Wasn't broke, didn't break the skin, so guess what?- we didn't run to the er, we iced it n it's was fine in a couple days. So am I a bad aunt n a horrible pet owner, no I'm just realistic n use scientific methods to form a plan of action. Had his finger been unmoveable or a compound fracture, as with an animal, ya we would b seeking help from a trained professional. My advice to you is to request some antiinflammatories from your vet, ice the injured paw, restrict the cats activity as much as possible (try confining the cat to a bedrm or bathroom), make all needs for the cat easily accessible, and give ur kitty some love. If there is no improvement or the cat is getting noticeably worst, go in for a vet exam. N for the owner of this pet, I'm so sorry so many idiots have the ability to post n for u idiots that post, find something to post about that ur actually knowledgeable about, otherwise u just sound ignorant!
