Humane Society of Greater Akron. They are running a special right now on adoptable cats at their brand-new facility on Darrow Road (Rt 91) in Twinsburg. You can adopt a fully vetted cat (neutered, all shots, and microchip) for $10.00 to $19.00 depending on when you show up. You pay the price according to the time of day- for example at 1:00pm it's $13.00- get it?. (The regular price for adult cats is $50 and kittens are $75.) You can find their cat listing on Petfinder.com.
If that's not a Frugal Friday tip, I don't know what is! :)
