Homecoming to a new environment is very stressful for a kitten, give it reassurance and time to adjust to the new surroundings before making introductions to other animals in the household. Make sure all the doors and windows are closed and that there is a guard in front of the fireplace (a dark quiet chimney can be very inviting to a nervous kitten).
Make sure that the kitten knows where the bed, litter tray and food bowls are.
The kittens‘ bed should be a refuge to retreat to if things become too stressful.
It needs to be warm, dry, comfortable and draught free. There are many types of bed to choose from or you can put some warm bedding inside a strong dry cardboard box with a hole cut in the side.
Putting it in a warm secure corner (near a radiator in the winter) will make it welcoming and the kitten feel secure. On the first few nights a warm water bottle under a blanket may help to compensate for the absence of the kitten’s mother or littermates.
If you happen to have, or can borrow, a large pen (a kittening pen or the type of metal pen used to hold dogs securely in the back of a car) this is ideal for providing a safe den for the kitten and can hold its litter tray and bed. It is also an excellent way to introduce other animals.
