Cat Limping! Help?

I just woke up about an hour ago.  When my cat started walking over to me I noticed that he was limping really badly.  He isn't putting any weight at all on one of his paws.  There was nothing stuck in his paw, I guess he could of broke one of his legs somehow!  What should I do?  I can tell it is clearly hurting him to walk, but he's still doing it.  

Please take him to a vet! There are many clinics that are open on Saturdays (though not for full business hours). Call and let them know what happened and they may be able to squeeze you in because it's causing him so much discomfort.

I will ASAP.  I have to wait 3 more hours for my dad to come home.  Thank you for the quick reply!

Great to hear. Make sure you call them in advance. Even for emergencies, it's just a reality that Saturday appointments fill fast (I always call a week or more in advance if I need a Saturday) so they literally cannot get you a time slot. You may need to be referred to a different vet that may have openings, or even the emergency vet. Always best to know before leaving the house to avoid yourselves and your cat the inconvenience of bouncing around. I've been in those shoes before!

How old is your kitten? Did he recently have a vaccination. There is something called limping kitten syndrome. They limp and the limping goes from extremity to extremity. They can have so much soreness that they can't get to their food and you have to hand feed them. It lasts just a few days. Is this what is happening?

Sounds like your kitty has Patella Luxation which causes the kneecap to rotate out of the groove its suppose to ride in. 

Hi @TheGreenester, are there any updates on your cat's limping or contacting/seeing a vet?

It is impossible to make a diagnosis online, but if he is still limping after a few hours and there is nothing obvious wrong (like a thorn in the paw) he needs a vet. It could be so many things.
