Hi, I have a female Columbian BCI. I got her on September 25, 2010, and have been feeding her adult mice from Petco/Petsmart once a week, almost without fail (went on vacation once). I think the mice from Petsmart might be getting a little small for her but it's difficult to tell. I know, I know, the rule is that the prey should be as big around as the snake is. These mice are approximately 20 grams, according to the packaging. The next size greater of food is the small rats from Petsmart, which supposedly are 40-50 grams. I don't know exactly how big they are in comparison to my boa since I didn't want to buy them if they were too big. I was hoping that someone with experience using Petsmart frozen rats could take a look at this photo and video and give their opinion. Should I keep giving her adult mice for now? Ordering rats online seems a little inconvenient, especially with the high shipping charge.
