My ball python refuses to eat rats! It is so frustrating.

Here is my breakdown: I only feed frozen/thawed as I bought her while she was already eating the frozen. I've had her for just over two years and she has been quite the good eater for most of it.

There was a time where she went on a hunger strike and that was when she was getting somewhat big on adult mice so I tried switching her to rat pups that were the same size to begin her transition to rats. She would not take them, but due to the somewhat large supply of pups I kept trying them until they got freezer burn and I had to throw them away.

Since then I put her back on mice and she takes them down like popcorn. I am feeding her about 3 mice a week, but not in the same feeding. Approximately one adult frozen mouse every 2-3 days.

I've tried offering her small rats every once in a while but she won't even go near them. Has anyone heard of a ball python being so picky?

I am frustrated and need advice! Save me!
