This is a quote from a herp forum I go to

Yes, you can overfeed a tarantula. This is a common cause of death (in captive specimens), particularly in adults. Many, (I hesitate to say most cause I'll get yelled at) captive raised adult tarantulas are over fed. I really don't know how to describe what a "fat" (for lack of a better term), abdomen looks like. It should be firm but not over inflated looking. Adult tarantulal are used to going long periods of time without food (yes, there are exceptions) and then gorging themselves when food is available. If yours are still growing, a couple or three pinks at a feeding will probably be fine, but this may be a little much for full grown adults. Hope this is a help.

I am sure Joy will find it amusing
