I have 2, they?re both 11
So very different in personality and temperament.
Their names are very distinctive so they will be A & B
A came to us via a friend of a friend, they delayed taking their cat to the vet to be spayed when they did she was pregnant
. Third litter. (My 2 were at the vet the day they could be done)
A was pretty much handled from day one, his Mum was/is pretty laid back and he takes after her. He is the cat that curiosity was talking about.
Comes running whenever there?s anyone at the door wants to know what?s happening, loves lying beside you having his belly rubbed. Will let anyone pet/rub him. But will never sit on your lap ever, no idea why not. He came litter trained, they learn quickly from Mum
Loves reading, sounds stupid I know but whenever I pick up a book , he?s at my elbow, there?s obviously something about pages moving that fascinates him.
He gives great ?kisses? rubbing foreheads and will come begging for them. Has all the neighbours under his spell. He knows his name and comes running to it, also knows that if he is called by his full name, think Eddie/Edward, that?s he?s in trouble, will still come running and then do his cute look, and flash his fluffy belly. .
B is an unofficial rescue, basically we just got A as a kitten, and there was a knock on the door and a neighbour (little old man who has since died) thrust a ball of fluff at me saying ?you like cats, here?. She was about 5 minutes from being feral.
A littered trained B in about a day. Cats like to be clean in the main.
I have a friend who visits the house regularly it is only in the last 2 years has she seen B.
But she is more ?our? cat than A, she loves lap sitting and is Ms Chatty von Chatty to me and OH, will sit in the window and chirp & meow to you as if she is commenting about what is happening. She has never left the back garden (to our knowledge). We get a greeting when we get home, and told off if she feels we are late 
She has the warmest belly ever. . . OH and I will compete over getting her to sit on our laps in the winter because she?s like a little hot water bottle that never cools down.
Her best friend is our Hedgehog, she gets very vocal and agitated if you dare to go in the garden when Hedggie is there, and will try to herd you away from him/her.
You just need to be on top of flea treatment, hedgehogs are rife with fleas. If you have bird tables make sure that they are used to wearing a bell on a snap close collar from being a kitten.
Neither of them have ever been interested in chasing birds, to my knowledge, well never had any brought home.
A did have a period of trying to wake @ 3:30 am as a kitten. Lasted about 2/3 days.
He did it one night, padding at us, meowing, licking my arm (house is pretty open plan so couldn?t shut them out) fortunately we had a vet check-up the next day. I mentioned it, she told me each time he did it just place him on the floor/don?t speak/don?t acknowledge. As I said 3 nights, done, B never did this.
But both of them have always loved little kids, when my DNs were little they both came running when they came in. Both put up with a bit of rough handling, though we did a lot of ?gentle, be gentle? and cats are pretty good at running/hiding when they?re not happy. (B would hide if DSis came in alone, come running if she had Dn?s with her)
Anyway to specifically answer your questions to the best of my knowledge:
BROKEN NIGHTS: be strict either place on the floor gently but with as little interaction as possible or just don?t let them in your room, they learn pretty quickly.
DO KITTENS CRY AT NIGHT FOR THEIR MOTHERS? Mine didn?t, though I can?t speak for all. They wanted a safe place that was theirs alone. For us it was a wicker basket with a soft blanket that we sprayed some catnip on. A was already used to having his Mum sleep separately.
LITTER TRAY: As I said above Mum trained A, A trained B. If you keep on top of it , litter tray is a five minute job daily and a full change once a week for me. Despite both of them having full access to the great outdoors they both come home to poo. Crap for us
nice for the neighbour?s garden.
Thing is like every other mammal cats have a personality of their own
