So I have 4 cats, they're all indoors only as 2 of them have "disabilities" so they can't go outside. I've had 3 of them for 5 years, the other one was my boyfriends cat who moved in with us when he did, about 2 years ago, so they've lived together a long time now.
They don't fight between themselves, but they just destroy anything that they can, I live in a really small flat (was in a bigger place when I first got them), I can't leave ANYTHING out on a surface because it'll be chewed or knocked off or wrecked. They've eaten plastic bags, any human food that they can, wires, chewed wood, chewed my ipad, papers and cards, any packaging, they tip over the bin when they can and eat anything from there, I can't even put my birthday cards on display for example because they'll just get catted and destroyed.
2 out of the 4 also refuse to go to the toilet in the litter box, we have 3 boxes (very large ones and changed regularly with poops always picked out asap), one cat will go to the toilet literally infront of the entrance to the box, the other cat will poop in the box but urinate on anything soft like clothes, bedding, the carpet. The carpet has also been ripped up at the corners from the cats.
At feeding times they all have their own bowl and they're fed 2 times a day with good quality food, 2 of them are still overweight, they all beg for food as if they're starving. If I'm making food they are all under my feet meowing and begging and jumping on surfaces and making a mess everywhere.
I have a big cat tree for them to scratch and sleep on, and a sofa which is basically only for them (but the one cat keeps trying to urinate on that too), they have lots of toys and get lots of human attention from my boyfriend. I have feliway plug in which is a calming scent thing but it doesn't seem to do anything. The cats are loving to me and my boyfriend and want attention and cuddles etc, which they get from him, but I am starting to hate them for their behaviour. They've literally ruined my flat by constantly destroying everything. I love them but I don't like them at all, my boyfriend refuses to rehome them (I would gladly rehome the worst 2 of them at this point because I'm so stressed out)
They've never been outdoor cats so it's not like they're missing the outdoors and want to go there, and like I said they can't go outside anyway as if I leave a window open for the 2 normal cats then the 2 disabled ones will get out too and just die outside or be stolen. How can I make them use the litter boxes and stop wrecking everything? They've only been this bad in the last year or so, so I've put it down to the lack of space we have now while we lived in a biggish house before, but they only ever stayed in 1 room before anyway out of choice, and this is something that I can't fix at present
