There are many cats that get adjusted to the litter box you provide them, but there are some who are not happy with this at all. This may be due to the fact that cats are quite sensitive to the smell and texture of the box and therefore you need to get something that you cat will be happy with.
Presently, there are a large number of cat litter boxes available in the market. They come in a variety of sizes, designs and texture as well. On top of that there are also available covers for these boxes which will help to reduce the smell of ammonia which most cats do not like to stand. There are many cats who like enclosed spaces and especially when it is warm and dark in there. Therefore, you do not have to worry about training your cat to adjust to such environment.
Moreover, for your convenience, these days, companies have started to manufacture self cleaning litter boxes for cats. These litter boxes have sensors which determine how much waste is there and then gets rid of the waste by centrifugal motion or with a rake. These are very convenient for cat owners as they do not need to use a scoop to get rid of the waste material. Moreover, the sensors are not activated when the cat is inside.
When you are getting a box or a litter tray for your cat, you should always make sure that your cat will be comfortable inside.
