i do i have 1/4 hardware cloth

i had the bottles in the top but some of the rats were a little small and couldnt reach them verry well but as long as the bottles were in they werent chewing at the hole just that one time i got busy and forgot to put it back

its the chewing around the top edge that they are escaping from and they are all chewing at almost the same place (they must communicate with their minds)
