@Angie1403 they can’t kill the fish by getting at them, but they can give them heart attacks pawing at the tank.
Just don’t bother with the kittens. They’re only 1% cute, rest of the time they’re under your feet, forever running through every door you open, licking the toilet seat where the crud runs off behind it, licking their bum then sticking their head in your tea cup. Everything you pick up ro put down or move out of their way they’ll go for, every charger lead they’ll eat through, fur will waft through the air into your dinner, the fridge, kitchen worktops.
Yet ‘cat people’ seem to love all these skanky side attractions, they actually allow it. Cat food on the kitchen floor, litter tray all over the floor, kitten poop on your blinds, curtains, bedsheets,.... disgusting.
I recommend try before you buy.
But then if you’re one of these weird skanky ‘cat people’, you’ll forgive all this vicious behaviour, sadism and house trashing, because, like, for 5 minutes a day, it will let you stroke it while it purrs.
You must try giving it a bath with your bare hands too the first time (of many) it gets poo stuck to its rear end, if you think kitten bites are scratchy and sharp, nope, it’s like dog bites.
Enjoy the fantasy meanwhile!
