A cat has to give up a lot of freedom when the first children move into a household. With the crawling time, many cats no longer have free access to the stairs. While a young agile cat usually has no problem, even with an extra-high grating, many elderly fur noses are no longer able to jump over a grating.
Protection for the cat
However, there is also the other variant, in which a stair gate is to prevent the cat from entering every room and lying comfortably in the children's beds. Then a normal stair gate is of little use, because as mentioned, a cat can easily overcome 1.50 meters.
If she still has a starting place somewhere on a chest of drawers or a chair, she can also manage two meters. Therefore, it makes sense to build a suitable grille yourself for this purpose, which reaches up to the ceiling.
