If i buy online, I have to buy in bulk, but my ball python is young and growing and I don't know what sizes to get her. Also, petsmart only has mice, so that is what she is on, and if i order online, I want to get rats. What if she doesn't take to the rats and I waste my money? How should I go about ordering? My ball python is currently 109 g empty. As of now, she would need fuzzie rats, but soon, she will need rat pups. A site i looked at sells them in packs of 25, but won't she grow out of that size before she finishes the pack? I just need some help. She eats every 5 days (1 appropriate sized meal). I've had her for a month and a half. She was 96 g when i got her. She lives in a 32 quart tub. Great eater. If I did not provide enough info, just tell me.
