This modular is made up of 10 pieces (4 different) which have different uses. the internal parts are 3 different of which two of them are hollow and one solid. The center piece has 3 small holes that help to fix it on a wall, so that cats can play climbing, fixing them as if it were a ladder on the wall; the other two pieces are to be placed on the floor and one of them is hollow for small cats to play with. The largest piece is a 3-story tower and it was designed for families that have more than one cat, so that they are happy playing, climbing, scratching and resting. The shape of all the furniture is organic and comfortable for cats, due to its ergonomics being considered in the design and development process. Cats of all ages can use it, they are very safe and resistant. Has been very important for the cat to adopt and use it to prevent it from scratching and damaging the furniture in the residence, because many times this causes them to no longer love them and abandon them.
