I was really hoping to get the ratroom repainted before posting, which is why it has taken so long in the first place. However other home projects have taken priority, so here it is. =D
Boys - 6 Martins R-680's

Girls - 6 Martins R-680's

Geriatric boys - 1 Martins R-695 and smaller cage for two less mobile boys.

Geriatric girls - 1 Martins R-695 (the R-680 on top is another cage with boys)

The Nursery. I use these SuperPets cages as nurseries. They are easy to breakdown when not in use.

Individual rattie cages (pics coming soon)
