Hey /an/, a question for you.
Does anyone have any ideas for homemade modifications of a guinea pig enclosure? We have ours set as pic related but we're trying to find a way to cover his cage door so his feet don't get caught going in and out. He slips too much on the cardboard to use that.
Add some high grit sand paper to the cardboard
That's why I said high grit.
Popsicle sticks could work I guess.
I recommend an entirely new enclosure. C&C cages aren't expensive.
