My two guinea pigs have 2 burrow pickets in they're cage wich is basically a price if felt that's then looped over its self to allow them to burrow. For the longest time pippa wouldn't use hers but now she fights cleo for hers. No blood or scratches but the both push into the blue pocket then site for a few minutes before a high pitched squeak and cleo is forced out. There's a second pocket but the won't use it. I've tried swapping the locations of each pocket but then they use the one on the fight over location and ignore the other. I'm not sure what to do as Cleo feels safe burrowed and is happy so I don't wanna remove it but I don't know what to do
