Bunks and a little on activities
A 14-week-old kitten still sleeps a lot and you must respect her sleep and leave it alone when sleeping / resting.
Cats like to sleep high, and although few people think that cat trees are pretty, they are smart because they fulfill several functions. Choose a tall cat tree with large cave, good thick scratches, large hammocks and a cozy basket at the top. The cheapest cat trees do not last long - Zooplus.de is somewhat cheaper than the Danish Zooplus. The selection is the same and it is good solid trees. Decisions from the beginning, where the kitten is allowed to be ... is it allowed to be in bed, on the sofa and on tables, this is what it does. Cats can be very persistent and insistent, but they can learn everything - also that they must lie on a blanket on the sofa. Move the kitten quietly to its place. Choose a sound that is easy to say and use it when the kitten is doing something good or something she likes, and maybe enhance with a little treat.
Brits often get warm so they love to lie in the bathroom sink. They also like to lie stretched out and like on their backs. If you want to transport the kitten (eg to the vet, in the cottage etc.), then it is a good idea to offer the transport box as a place of residence, so the kitten is used to the box. When the kitten is awake, it must be activated / play ... tease sticks, most kittens can not resist, felt balls (sisters Grene) they are fond of, activity boxes where they must try to get out treats, is a hit. Cardboard boxes with holes are also a cheap toy. Small soft balls that jump, different small soft toys with catnip are also nice - play with the kitten, but let it also play / activate itself. With small soft treats as a reward you can learn it: to come, to get things, to give "High five" and much more. The more the kitten is activated, the quicker and more active it becomes. Adult Brits may also like to play, so keep up the activity if you want a cat that does nothing but sleep. The British is a muscle cat and it does not get muscle from lying on the couch…
