Those sizes sound fabulous! Lucky bunnies and lucky guinea pigs
I love getting new housing for animals, it's so fun and the animals appreciate it so much
You've made me jealous!
Are they currently outdoors? Just thought it might be a good idea to mention that if they're currently indoors, they can't be put outdoors until at least March/April when it gets much warmer. I'm sure you already knew that as you obviously are clued up about housing sizes, but it sometimes pays to say these things!
