I suggest looking for a good vet first of all...and treats!! Although you have to remember not to feed too many treats, no matter how much the kitty begs. Just about 5-6 treats per week, although less is better.
I also suggest having a little kitty first-aid kit in the house. I think they are really good, especially for kittens because they are often very curious and get into trouble! I think it should include:
Body Wipes (found at most pet shops)
Gauze (found at most drug stores)
Small scissors (found almost everywhere
)
Kitty Eye Drops or other eye products that treat general eye infections (found at most pet shops, there's one from Dr. Goodpet that has always worked for me)
Your Vet's Card (ask your vet for one, always go to your vet for any problems)
Kitty Ear Drops or other ear products that treat general ear infections (found at most pet shops, there's one from Dr. Goodpet, never tried it but it should be good)
Hydrogen Peroxide (found at most drugstores, really good for minor wounds)
Clean blanket/towel
Cotton Balls or Pads
Tweezers
Other medications recommended by your vet.
A small book on cat diseases, or some pages on cat diseases printed online, so you can recognize what's wrong with your cat and what to do
Thermometer
Adhesive Tape (found at most drug stores)
Latex Gloves
Flea and Tick Treatments
You can keep it all in a case or box or whatever, and whenever your cat gets hurt or sick you'll probably know what to do. Remember though, it's just for before you call your vet, if there is any problem always call your vet, but use the kit while you're waiting. Also, always replace any meds when they expire.
Also I'd include: brush, and nail clippers.
