Callibator adopt guide

So, this is for a species I created, Callibators! Created somewhere in the sewers of New York, a mix of bat, cat, alligator and a little bit of radioactivity form this odd creature. They don't like people, and are rarely ever seen. They're active at night and hunt in small groups, in pairs or alone. They prey on rats, mosquitoes and other pests, even though people consider them to be pests. Callibators tend to be naturally colored, but those with more radiation can be neon. They are born in litters of 3-6 eggs, and can live up to an astonishing 40 years, but ones with more radiation can live from anywhere from 6 years to 80.
