The best guinea pig I have personally seen so far. It's big, looks visually nice, and has a great unique selling point: namely equal to 3 inputs! My guinea pigs love it from one side purely run and by another exit out to hobble back. So that also awakens the play instinct and provides more variety than if it had only one input.
Even the price is cheap, so there is of me a full purchase recommendation for all guinea pigs friends.
