Harmony House's fee (the shelter from which I adopted Cassie) is $75 regardless of the cat's age.

My best friend's cat is from the West Suburban Humane Society, and their fees are a little different:

Adult Cats - 1 year to 5 years old - $125
Mature Cats - 5 years and older - $75
Kittens - Up to 6 months old - $150

Take advantage of our 5-5-5 Program. Any person 50 years and older, that adopts a cat 5 years and older, can do so for the fee of $50.

We also offer an Adopt A Buddy Program. Adopt any cat and/or kitten for the regular adoption fee and get a second cat/kitten for half of the regular fee. This offer is good for up to 6 months after the first adoption.
