How can I cell?

Is there a local animal shelter? Sometimes cats and dogs homes will take small animals. Have you tried putting adverts in local pet shops? I don't know how old they are but I think that at a certain age you have to separate the females and males so they don't start mating or fighting. Are there any schools nearby that might fancy a class pet? Maybe an advert in your local paper or put notices up around town? If you can't find any takers try phoning your local vet and asking for advice about what you could do with them. I once found a budgie and had no idea what to do with it. I called my vet and they said they had a veterinary centre nearby where people could take unwanted animals. Good luck.

I think selling them to a pet store is not really bad...
