Some people just dont know they are doing wrong. Not that it excuses it.

At least snakes have other forms of vision such as there heat pits and jacobson organ. Blind humans will be much worse off compared to a ball.

At least she looks nice and round and she is in good hands now. Im sure she will live a very happy snake life for the rest of her life.

Good job on your behalf for taking her in.

Hope it goes well for you both
