There are at least 2 rats at Leeds RSPCA that need homes. Both boys, and they are apparantly very tame. Leeds RSPCA usually re-homes rodents for free i.e. no adoption fee.
There are always loads of rats at York RSPCA, not to mention, mice, hamsters and gerbils. My rats from there were as many as I liked for £5.
If anybody is interested and needs any help, let me know. I can usually find rescue rats in other parts of the country too so again if I can help, e-mail me at
