A cat will not understand a "wrongfullness" in urinating, so scolding will not help if your cat doesn't use the litter box. A cat will instinctively attempt to locate a soft and absorbent material to pee on, so with a feral cat it would be a matter of getting the cat to prefer the litter box to other materials. Perhaps by minimizing the other options until the cat is comfortable using the litter box.
If a cat who already uses the litter box suddenly starts going outside it, there is some reason for the change in behaviour, since the litter box would be the cat's preferred toilet too. Then it becomes a matter of figuring out the reason or reasons for the change in behaviour (a medical condition, pain while urinating, insufficient litterbox hygiene, environmental stress etc). Once the reason is found and fixed, the behaviour usually corrects itself.
Anger at a cat for urinating (it will not know people mean the place, just the action of urination) will most likely just make the problem worse, especially if the cause is stress or a urinary tract problem. Making the litterbox and urinating in it a positive experience for the cat will probably be the best.
2. Biting hard
With a feral cat that is unsocialized, this is bound to happen. I assume you mean biting hard while playing, not in defence or when threatened. You will need lots of patience. An unsocialized cat does not know how hard is too hard for humans. It will probably have learned how to behave and play with other cats, but not with humans. Slowly is the key. And training by rewarding good behaviour. When the cat plays as it should, it gets lots of attention and love. But when you see rough play coming, just leave the cat alone, move away and stop playing. No need for anger or aggression from the human, which will just confuse the cat. The amount of handling should be on the cat's own terms. For example, if the cat does not trust you to pick it up yet, don't pick it up. Think of it as a mutual training of how to interact with each other.
3. Destroying something
Again, a cat doesn't understand the concept of right/wrong in natural behaviour. It can't choose not to have a need to shed the excess layer of nail by scratching something so it comes off easily. It needs to do it. Or a teething kitten, whose gums are itching. It needs to bite things to get the baby teeth out of the way for the adult teeth.
The cat can't choose these things. The human has the choice here. If you decide to get a feral cat, make sure nothing you can't afford to lose, is within the cat's reach. If this is impossible, then a socialized cat would be better.
The risk to your belongings is much smaller if you provide for your cat's needs as far as scratching, chewing, knawing, running, jumping etc. with things that both of you agree are meant for that purpose
Both horizontal and vertical scratching surfaces. Things or furniture for the cat to jump on and climb. Things to chew and rip (our cats loooooove cardboard boxes to play in and to chew on - keeps the teeth clean too!) And things to chase and play with. A lot of these can be inexpensive or made yourself with a little imagination.
If the cat has the things it needs and (in the case of feral cats) knows what they are for, there's really no need for "destroying" anything.
I'm new here too, so welcome to the forum. Hope you find the perfect cat
