My BP Tillie recently shed and had a bit of a growth spurt. I haven't weighed her in a while, but I'm guessing she's around 300 g. She had been eating 2 rat pups per meal, but that looks way too small for her now - the lump in her belly is barely visible. The pet store I use suggested I feed her a small rat instead, so I bought some. The small rat looks about the same as the biggest part of her body, but is way longer than what I had been feeding before. I don't want to make her regurgitate ...or explode.. Thoughts?
