A cardboard box for the cat: Exploring something new in peace

One of the next November afternoons might look like this: it’s grey outside and a parcel is being unpacked inside. The cat watches from the other end of the room. You find the contents interesting; she may notice the empty cardboard box first. That can become a small moment of discovery if, after unpacking, a suitable offering remains. What your cat does with it may be left open.

Unpack first, then explore

Before the cat comes closer, you put scissors, plastic film, packing fill and packaging tape away. For a box you want to offer her, it’s worth taking a close look: PDSA recommends removing loose small parts such as staples and adhesive tape residues and choosing a size in which the cat has comfortable room.

Plastic bags should be kept out of reach. Cats Protection explicitly points out their risks. Our practical suggestion: collect all the packaging immediately when opening into a container that you then put away. That way it won’t be lying next to the box while you are already occupied with the new contents.

A clean, undamaged box without loose packaging parts is enough to start. You do not have to fill it with rustling material or decorate it with strings. If it’s unsuitable, put it in for disposal. Not every delivery needs to become a cat project.

An offer without demonstration

Place the suitable box stably on the floor and keep the entrance clear. Then step back a little. The cat may come closer, pass by on the outside or return to her own things. You don’t need to pick her up and put her in it, nor push the box to her.

Battersea emphasises that cats have individual preferences and that their environment should remain as predictable as possible. For this small experiment one can derive: offer a manageable change and leave the rest of the room familiar. You do not have to remove the previous resting place or rearrange furniture at the same time.

Perhaps your cat first peers in from the side. Perhaps she walks straight past. Leave the moment as it is for now. A box does not have to be accepted immediately just because you placed it there with good intentions.

Look more closely, expect less

Cats Protection describes boxes, among other things, as a way to hide and to view the surroundings from a sheltered spot. That explains why a simple box can be interesting for a cat. It does not mean that every cat will like every box.

As an observation idea you can pay attention to the small steps: does she stop at an edge? Does she look through the opening? Does she go in once and immediately back out? Such details tell more about the moment than the quick judgement “she likes it” or “she doesn’t like it”.

If she stays inside, you do not need to lure her through an opening with your fingers. Give her the space without turning it straightaway into a game of catch. Even if someone else in the household comes along, the box can simply remain where it is. The cat does not need a second demonstration.

A finished form for the box moment

If you want to incorporate the material cardboard deliberately as cat furniture into your living space, you’ll find at Fellino the BROCHHAUS JUNIOR designer cat house by cat-on. The freestanding cat house is made of corrugated cardboard and has openings for going in and looking out.

Compare the product dimensions with your cat and the intended location before choosing. Plan space in front of the openings and observe the product instructions. Even a finished cat house remains an offer: the shape and the material don’t yet tell you whether your cat will use it.

For getting to know it you can bring the same calmness as with a simple box. Put the house in place ready and let your cat choose her own pace. An enthusiastic reaction immediately after setting it up is no measure of whether the purchase will prove useful in everyday life.

The afternoon does not need a result

Perhaps in the end there is only a brief look into the opening. Perhaps the offer becomes something your cat returns to later. You can leave that decision to her without constantly adding a new incentive.

Keep an eye on the condition of the box or house and remove damaged, unstable or damp parts from use. Otherwise the new thing can simply belong to the familiar room for now. The interesting moment is then in observing: a familiar room has acquired a small change, and your cat decides whether she wants to explore it more closely today.
