Derma balls

[Morphie]

though hairless mammals do have their problems, I cannot agree that it is the same situation as a Derma ball. One rat bite and this thing is a gonner,and also because it is scaless, how do we know what temps to put it at?

rats... get rat bites all the time. The hairless ones are somewhat more fragile (it's recommended that you not put hairless rats in a metal cage, for example) - which is a situation homologous to the derma ball. It's a somewhat more fragile version of the wild type.

Also i don't find that rats have any real trouble puncturing even scaled snakes when given the chance... so i don't know why necessarily a rat bite = "gonner" for a scale-less one.

Just because the snake is scaleless doesn't mean it's not still ectothermic. You'd still put the temp at normal BP temps.

I feel that you're making a few stretches here to say that the situations are different to any large extent. :/
