I hate stores doing things like this
I once asked our local branch of P@H about them not selling any cages suitable for a syrian according to the RSPCA guidelines and was told they're just "starter cages" which is odd when no-one has ever been told this lol. I've since decided the branch doesn't exist though, so ours is exceptionally bad even for a P@H branch.
Some do sell the ferplast mary but at £60 its way cheaper to get a bin cage really
Amazingly the branch we use now when we go actually asked about the "rats" it was for and were fine when I explained it was to be a travel cage for our "russian" group. They even discussed bar spacing with us and were pleased when I told them we'd measured it and I'd checked that it'd be ok. This was in November and I have to admit its made me like that branch
