I can't visit the re-homing centre as I'm at college.I was also watching that video at the Pet Shop and it said that Cat's don't like tap water they prefer filtered water :O also not to feed them lots of Tuna as it lacks something that they need (Can't remember what it was) Was quite interesting just stood there watching that aha
