Home cats and cats that do not have the opportunitygo out, you need to sharpen the claw somewhere. And if the apartment does not have a scratching pad, then under the "hot paw" get the sofas, carpets, furniture and everything else that can be scratched. For the sake of justice, it should be noted that the presence of a scratching pad does not at all mean the complete salvation of your furniture from sharp claws, but still significantly reduces this probability. Dutch designers made a special Krabhuis for cats, that is, in translation from the Dutch House for scratches. This idea can be used to get a scratch with the house with your own hands.The house with a door, a window and a chimney wasdesigned for cats and cats, so that they play in their own pleasure, gnawed and sharpened their claws. This eco-friendly scratching machine with a house made of 90% recycled material - corrugated cardboard. That the house could last longer, and also withstand the weight and pressure of the cats, the roof and the bottom consist of 48 layers of double-sided cardboard. Of course, such a game complex is not eternal, the constant impact of the claws eventually leads to a house in a "non-residential" state. But the claws of artificial materials quickly fail, but are quite expensive. A similar house in Holland is inexpensive, but we can regularly do it ourselves with cardboard. If Krabhuis is perfected by craftingdoor, the handle having made more windows, then such a house could be used as a mobile carrying of animals. I think that cats and their owners will be happy, and the soft corners and furniture will remain intact and safe, which is especially important for those who live in a rented furnished apartment.
