Can you attach a mouse to a tablet
I suspect so on some models. Best Buy would help you with this. I use a stylus and it works great
Yup, if the iPad can, so can any other tablet( actually only a few lol)
You can but, it may not stay there, not that I'd want it to stay there, pooping and piddling.... I'd consider a small cage, where most people would keep a mouse. It's more hygienic.
