That means cats must have a daily visual contact with other felines, and hamsters or guinea pigs must be kept in pairs.
... So, that means that if you have a cat that HATES other cats, you have to piss it off once a day, every day?
And I haven't had hamsters or guinea pigs, but I have had lots of pet rats. Several times I've bought them in pairs as babies and raised them together. Which is fine, but I've also had one half of the pair die. So the first time that happened I thought "well, maybe he's lonely now, I'll get him a friend." and ended up buying a new pair of babies. Ended up with old rat in one cage and the new pair in another cage. Old rat hated the new ones. Which brings me to my point, what happens when one of the pair dies? Do you have to kill the other one? Or let it kill the new one? Or what?
Animals and guns. Two of those things that really should not be legislated by people who don't know *expletive deleted*it about what they are legislating.
