My “newcomer” kitten is extremely shy. What can I do?

It is only normal for a new kitten to be shy when it first arrives home since it is a new environment. One thing you could do in order to help it adjust as quickly as possible to its new surroundings is to slowly start exposing it to your house.
For instance, you may firstly begin by putting it in a small, quiet room. Try not to lose your patience! When it’s ready for affection it will surely come to you!
