A problem with letting a guinea pig have the run of your house or if you have them on your lap is that they do tend to pee and poop. They have the ability to hold their bladders for 15 minutes before they have to go, but they cannot last longer than that.
So one of the things that you may be wondering is whether there is something like a diaper that can be put on a guinea pig to stop them pooping on your carpet or worse still on your lap.
The thing is with guinea pigs is that they do not like anything attached to them like this. They are also very clean animals and will get very uncomfortable with having their poop and pee still close to them. It will just distress them.
Unfortunately, its just one of the things we have to accept as owners that guinea pigs will poop and pee and you just need to be one hand to clean it up. Their poops are very small and solid but very easy to spot and their pee is in very small amounts so is very easy to clean.
But whatever you do, don’t put a diaper on them.
