I truely would hate to think that you are considering declawing. It is illegal in most countries, we just haven't caught up yet. Declawing will cause you more problems than ripped clothes. Like a wet bed or couch because declawed cats don't like the way litter feels on their feet and they tend to look for softer places to go. They also can get quite "mean" because they have no defense on their feet and tend to bite more. Again - I think shredded clothes is a better option than cat bites. I would search best you can to try to find something to block that closet - folding door, shower curtain, anything and get some scratching posts - both vertical and ones you put on the ground ($10 at walmart for these. They are cardboard and come with catnip. My cats go nuts over these!). I've got 6 cats and not one scratch on my furniture (or my clothes), but with that said - they were babies once and babies will be babies. They will grow out of it, but they're little now and just want to play. It's like I tell all our adoptive parents when giving them advice on what to get - "I hope you aren't to attached to your curtains"
But please, please don't declaw them. It's a terrible thing to do. It's not a nail removal, it's an amputation. Anyone wanting to adopt from us that is considering declawing I ask them to go have their toes amputated at the first joint, then come back and see us about adoption.
Think of it this way - if you had adopted a puppy instead and the puppy was chewing up your clothes - you wouldn't have his teeth removed would you?
Please understand I'm not trying to lecture - just educate.
