Took my DDs to a small rescue centre for the afternoon, loads of animals there so more like a mini zoo. They don't sell animals they just take them in and 'care' for them.
All was well till we looked at the birds... I was wounding what on earth rabbits were doing running round the averies but since I don't know anything about rabbits I figured I could be wrong and maybe it's ok? Until I saw Guinea Pigs running round too 
I am going to write them a letter and just wanted to make sure i have my facts right!
GPs are prey animals yes and being in an avairy would not be comfortable for them?! In fact they would probably hate the fact birds are flying over their heads and shitting on the bloody floor that they've got their little faces so close to?!
Sorry- that turned into a bit of a rant...
