First of all, don't ever get a Bengal cat. They're pretty much guaranteed to act quite a bit like your terror or worse.
Living with a Bengal of my own it all sounds pretty familiar and normal to me. I like it though, Nikita makes me laugh every day so I put up with her antics without any hesitation. So yeah your cat is not wrong or a bad cat or anything, he's just a higher energy feline than you're used to.
To curb the most annoying things it really helps to realise that your cat is a cat, and a baby one at that so the way you deal with him is different than you would with human babies or puppies.
First of all like has been mentioned cat's don't really do negative reinforcement. Holding him under the sink or spraying on him all the time won't make him realise he's doing a bad thing. Their brain often just isn't wired that way. They don't connect those dots.
Basically he thinks that randomly you do nasty things to him and doesn't really figure out why, or if he does make the association it's associated with you more than the thing he was doing. So he might figure out that for example climbing the drapes is a bad idea but only if you can see him do it.
Hissing on them can work though, that's something mother cats and other cats do to communicate so then you're speaking his language and he's a lot more likely to understand.
The urge to please their "pack" leaders or members isn't there in cats since they're not really pack animals. So they don't really get the concept of you being unhappy about anything they do. The urge to submit a bit to mama cat is there though, especially when they're young and since domestic cats are in some ways always eternal kittens (even when they grow up into big lazy cats) correcting them like that can work.
To get through that hyper kitten stage redirection and physically blocking things off is vital. It sounds like he's filled with energy and playing lots with him should help you a lot.
I needed to play with my cat for over 2 solid hours a day when she was a kitten. Often cats who are destructive do so because they don't have a constructive outlet for their energy. The Da Bird toy is absolutely fantastic and well worth buying, Cricket should love it as well. Get your meezer tired enough from play and he should zonk out and give you a time out.
Another thing is giving him paper boxes to explore and a nice big cat tree to climb and play around on. Basically try to make the allowable places more intersting for him than the not allowed parts.
If he likes digging things up you could hide food treats in toys like the Peek a prize one: http://www.drsfostersmith.com/produc...m?pcatid=10239
And also maybe get puzzle balls to put the dry food in if you feed them dry food. It means he'll have to work a bit for his food which should leak some energy from him.
Here's the Da Bird toy http://www.drsfostersmith.com/produc...3&pcatid=11643
It's an absolutely fantastic toy, the head spins and whirrs when you make it move which drives the cats absolutely nuts. If you get it you'll have to hide it away when you're not using it to play because otherwise the head will be torn to shreds immediately. I have actually bought 24 da bird refiller heads for my cat now (she's only been through around 7 so far, the rest are still in storage)
Another example of what I had to do, I had to remove all curtains from my house because Nikita climbed up them, I used the wooden shutters instead and got a wooden board to put in front of the window that didn't have a wooden shutter.
She also used to unplug my laptop but has fortunately grown out of that, or she has made piece with the computer, I don't know! heh
Anyway good luck with your cat and please let me know if you have any more questions and also just to update with how it goes.
My cat has full claws (fairly visible from the signature) and I want to thank you for not having declawed your kitten. There are other ways of dealing with 'problem' kitties, fortunately since declawing is defined as animal abuse and is illegal in most of Europe, including where I live.
