If your guinea pigs need something to chew on then one of the things that you should probably avoid are plastic bags.
There are three good reasons for this;
- The reasons are that they could get stuck in them if they play around with them.
- They are not the best things for guinea pigs to chew on as they can be chewed into smaller pieces which are not easily digested.
- What they are made of is not especially healthy for guinea pigs
So if you are looking for something for guinea pigs to chew on, then steer clear of giving them plastic bags. There are much better things for them to chew on, such as cardboard or paper which will be much better for them.
