i try and stay away from any animal cages at pet stores these days just so I don’t come away with a ham or two
i do agree the advice on Chinese needs to be changed they should say that although they can be social there is high risk of fighting particularly with females.
why cant they let the rspca deal with rehomeing these poor animals at least the new homes would be vetted then so the same mistake would not happen again
as for unwanted litters i would never take on back to p@h I would rehome them myself as I would fear who they ended up with and the conditions the would have to endure at the store. And the same thing might happen again knowing p@h.
