Here's a tip for the future since it sounds like you got it all done already. USE ANTI-SIEZE!! That stuff will make sure those studs will never do that again. It can be found in any auto parts store for like 2 bucks. Make sure you put some on all the threads on each lug. You souldn't have to reapply the stuff for about a year or so depends on how often you take your rims off. Always use a breaker bar or the jack bar method that most jacks come with now to break lugs loose. The leverage of those long bars makes everything alot easier.
Sorry to hear about the cat. Get a car cover!! That way they can't leave hair, claw marks and prints all over your precious ride!! Trust me it's worth it.

Good luck.
