I agree with everyone here. We all know that hamsters should make their pet spiders clean up the mess made by their pet rock since rocks have no arms. However, spiders get so confused over which legs to use. It's time consuming waiting for them to decide which of their 8 legs should be mopping up all that puke.
If you want the mess cleaned up before it dries and becomes all crusty, you have two options. Either, have your child clean rocks puke up or do it yourself. But, don't forget now that rock may be feeling a little under the weather. Find out where the mouth is and take its temperature.
Oh, and when you do find the mouth...Let me know the location. You never know when I might need that little bit of information too. lol
