As long as Chi Chi is a He He it shouldn't cause problems of him thinking its a nest and laying eggs later in life when he becomes sexuly mature, let us know how he takes to it
I don't have that, but I have a happy hut (tent shaped). Auggie loves it.
Be ready though to be assaulted at any moment by the nay-sayers. There are some concerns to be aware of with any such huts - but in my (limited) experience they seem DRASTICALLY overstated.
Do keep an eye on the sack's condition and remove any fraying threads or material.
I saw those in Pets at Home last night and I ummed and ahhed about getting one for Cal. I didn't in the end but it's still really rather hot here at the moment. We'll see when it gets colder.
I got her a rope toy though....she loves her wooden ones so this is new to her lol.
I have one of those for Levi. He loves it! I used to have it in his cage, but it resulted in some cage aggression, so now it's in his window, where he spends time everyday. I have to say it's probably Levi's favourite thing in his world!
