If you have a new kitten that is standoffish, there are many things you can do to get the kitten to be comfortable. It is important to give the kitten a lot of attention, and play with them often. Giving them plenty of toys and objects to play with, will help the kitten become comfortable.
They make a product called Kitten Attract that is in litter form. You put that in their litter box and the kitten should go right towards it. That's probably the easiest way to get the kitten into the litter box without forcing them.
I have a male black kitten and I named it Leo but his full name is Leonardo. Give your kitten a name that you'll be comfortable with for a long time. The kitten won't worry about it. There are no rules (shoulds).
It depends on the type of kitten you are planning to get as well as if your current cat is generally friendly towards other cats. If you do end up getting a kitten, when you introduce it to your home leave it in its kennel for a little bit while you let your other cat sniff the kitten. The kitten will probably become a little scared, but trust me, it is much more overwhelming for them when the kitten is not in the kennel. After both cats get a sense of who the other cat it, you can let the kitten out of its kennel. Other than that, a kitten should be fine. Also, make sure you spread your time equally to both cats or else your current cat will get jealous and most likely act meaner towards the kitten. Good luck :)
Maybe you are hearing your cat purring. This is what cats do when they are comfortable.
YUP it doesn't like you and it is not comfortable with you
Make it comfortable. Without really knowing what is wrong, it's all you can do. Make sure it has plenty of water available and a quiet, dark, sheltered place.
The human's behaviour towards it.
Your kitten is unfamiliar with his or her new surroundings and will come out when he/she feels comfortable ; just be patient .
Unless the kitten has some disease then no
There are some diseases that a sick kitten can pass on to make a child sick.
Probably about 1 year . You can make one unless you get your mama cat fixed then you cant make a kitten.
Yes. A sick kitten can make other cats sick.
