Cay destrusctive behaviour - at the end of my tether

Snuggles

Most cats hate being shut in. All of the doors in our house, including the bedroom door, are always open so the cats can come and go as they want. Yes this means I get woken up at 3am almost every morning by one of my cats wanting to snuggle under the covers or just wanting a bit of fuss for five minutes. The alternative would be her trying to batter down the door all night, which would be much worse.

Whilst some behavioural issues can be improved, you can't stop a cat being a cat. If I was terribly worried about carpets, furniture etc being scratched/damaged, I would never have got a cat.

We have two indoor cats who are shut into the kitchen overnight; one will sometimes scratch at the door for a few mins initially, then get bored and go and chase a ball around or something. The other is elderly and not bothered at all. I don't have any specific advice about your cats behavioural problems, but I wanted to post to say that it is possible to do this successfully, though I'm not sure how best to suggest that you get to that point. If it helps at all, when I was young we had an ex-feral who would attack randomly and she did calm down as she got older...

My 2 cats are indoor (mainly decided this as their breed doesn't fare well outdoors - they are Ragdolls), but must admit, I wouldn't ever confine them to one room! They can access every single room in the house, 24/7. I feel bad enough having to keep them inside the home, even though it is for their own good and recommended with this breed (I even had to sign a contract with the breeder to say I wouldn't let them out)  - no way would I stop access to any part of the house. They can come and go as they please into our bedroom at night, and most of the time they do choose to join us on our bed. The only behavioural problems we've had is urinating outside the litter trays - but even this is most likely down to him suffering from a UTI when he was very young (the behaviour kind of stuck!) The other cat has 0 issues. 

Was he an indoor cat in his previous home? It is acceptable to bring a cat up as a house cat, but it is different if the cat has known life as an outdoor cat. I would not expect a cat that is used to going out to be happy staying in.

Our younger 2 are indoor cats (breed and how they've lived). We cannot go anywhere even the toilet with the door shut without one or the other waiting outside the door for it to be opened. If a door has always been opened, it will be a fight to close it on them as they will expect it to remain open (plus it becomes more intriguing if it becomes closed).
The oldest was an outdoor cat until about 4 1/2 years ago (I mean proper roam the countryside, hunting playing in rivers etc) but came to live with us as an indoor cat on a permanent basis. She took the change well as there was enough to keep her amused and occupied (even if it was watching the world go by outside the window) and is enjoying her retirement.

Sounds to me as though you dont know cats very well.
I doubt they have behaviour issues....I mean we shouldnt project human issues onto animals.
They sound bored......and cats dont like being shut in.
