I'm gonna stick to my guns on the rats thing here. Agreed that if one animal can take oversized prey items it would be a Burm but in this case the Burm is obviously grossly underweight and in my opinion (and only my opinion) giving a prey item larger than the diameter of the animal is stressful and should be avoided in an animal that is already obviously physically stressed. It's not my animal and the OP can of course feed whatever he likes but if it were mine I would stick to rats for a while. As the old saying goes "if it ain't broke, don't fix it" it's eating well on the rats and gaining size why screw with the equation?

Along those same lines...everyone is saying that rabbits are better nutritionally than rats. Can anyone support this factually? Not just "I heard from a friend." I'm definitely not saying rats are better or rabbits are worse, I truly don't know. I simply have never heard that and would like some "in writing" proof to support the statement if anyone has it handy. Thanks
