My sister introduced me to cat welfare, where I got my adorable kitten Boo. This place is dependent on donations, both monetary and physical (food, toys, litter, etc).
It's a no-kill facility, so any cat that isn't adopted simply makes its home permanently at the shelter. Kittens run about $70, but it's well worth it because that includes all shots, tests for diseases, and when the kitten is old enough, spaying or neutering.
Older cats cost less, but need your love even more. When you walk in, most of the cats are roaming around or sleeping in the sun. I go in often simply to visit with the cats and give them a little love.
Don't go to the pet store when you can get an adorable, and affordable cat at Cat Welfare! It's worth the trip!!
