Doesn't sound to me like there was anything wrong with that kitten.
Kittens have tiny razor sharp claws and they like to climb people and scratch people. That's totally natural. As far as the piss goes, they are super easy animals to toilet train. They toilet train themselves. All you have to do is put a litter down and keep it fresh... but it will take a good month or two. When an animal pisses on tiles or concrete or floorboards, it is going to spread out into a big circle. Same thing happens if a human pisses on the floor.
Sounds like you were experiencing high levels of anxiety. I don't know your story. Are you schizophrenic?
I had a deaf albino cat called Cloud many years ago. She was a very scratchy cat, but she was fucking awesome. Very eccentric little animal. I loved her to bits until one day I ran over her while on LSD (me, not the cat).
I've had about 8 cats in my life, including the two kittens Sweetheart gave birth to... even though I gave them up around 6 weeks old.
When I lived in Africa, we captured a stray kitten. It was following it's mother around, but there was no love or support there. The mother was very sickly looking. So, we grabbed this kitten and fattened it up and taught it to wee in a litter then we gave it to a little girl.
Strays can be difficult. Kitsly (the name we gave our rescue kitten) was very scratchy, like Cloud. She was a feisty little cat. Tons of personality. Lots of energy.
I have loved all my cats.
Two of them are still with us, although one of them has lost a leg now and is getting quite old and sick.
