Ive give her a habistat now and its worked great, 91F.

Also, shes about 2ft long and does seem a lot thicker than the 50gram mice im feeding her, but they seem to go down well.. What should i do? Upgrade to like 100gram? It just seems abit big for her head to handle :/ I know id feel uncomfortable eating something that big if I was her size..

Is there not a chart? That tells you what size royal should eat what size mice? Theres the munson plan for cornsnakes..
