Like I've said 100000 times I'm no expert on snakes, but the only thing I could see that might matter, is that it's cooked, rather than raw food that they're used to eating. Cooking starts to break down the proteins and what not. But I'm sure as a little treat it mght not hurt

(Like we don't give our dogs/cats little scraps of human food, which isn't made for them, and is cooked...)
