I have at least 2 ball pythons that like to keep me on my toes.
One of my female pastels is a real pain. When I first got her she switched from f/t mice to f/t rat pups for me without issue. This was going great for a while until she decided she didn't like them any more. She will take the f/t rat like she is going to eat, she even tries to kill it again, but then she will not swallow it. She will eat live rats just fine though.
Then there is my female cinny. She couldn't get more annoying if she tired. When I first got her f/t rat pups were the bomb, she would take them like a child does candy, then like my pastel she mysteriously started hating them. Unlike my pastel she would only take live white mice (they did have to be solid white too). Now she is back on f/t rats. I prefer to feed f/t rats so I will offer it even if I think it's going to get refused and then feed live a day or two later if I am refused.
So what are your horror stories of picky eaters and how do you handle them. Do you practice tough love? Do you cater to their moods?
