Yeap!!!
Why they are called aquarium / terrarium???
But because they are good at holding "humidity" & "water". May be great for plants, fish, reptiles BUT not good for mammals... especially ones (bunnies, guinea pigs) that have similar body temperature like us.
Why can't people use common sense that why a glass petri dish is used to encourage bacteria growth or why humans do not live in a "glass" house???
The environment you/we humans) do not want to live in, please do not try to house that environment to our beloved
GPs.
P.S. and at $300 plus... how many C&C cage can you built??? That and plus the vet visits money from the URI the
GPs will almost definitely get from that. Geez... it is not even money "wise".
