Today I found the white-ist one UNDER the guinea pig cage. It is quite small.
In it's struggle it had dug quite the little hole around itself.
No trail leading to that hole.
No wire broken
MOST of the holes are less than 1 inch.
This is a fully wired cage. not wired great, but wired sufficient to hold piggies and the odd rabbit.
It seems fine, though rather smooshed looking. Will give him a good check over in the morning once the dents have a chance to "undent". Once I got him out (which took some maneuvering to do with out causing damage (cage is HEAVY) and set down he wobbled twice and then ran squeaking to momma.
