Everyone who has a cat has had it happen to them: they buy their pet some fun toy or a cat tree, bring it home and set it up- only for your cat to go straight for the box it came in instead.  So why do cats love boxes so much? Cats’ affinity for boxes is likely based in their natural instincts.  Cats are both prey and predator, and boxes can help fulfill the needs that come with being both of those things.  From a prey perspective, a box provides cover from prying eyes- they’re great for concealment.  For this exact same reason, cats may also be drawn to boxes from a predator perspective.  Most cats are ambush predators, which means they lie in wait in a hiding spot until just the right moment comes, and then they pounce.  You can use this knowledge to your advantage during playtime to keep your cat more engaged- if they go into a box, try slowly dragging a wand toy past them and see what happens. We’ve all seen cats try to cram themselves into boxes that are too small for them.  One reason for this may be that they want to get warm.  When we cover ourselves with blankets, they help reflect our body heat back towards us- cats may do the same with boxes, and the smaller the box, the better!  Your cat may also just be acting playfully- maybe they are sticking their paw in that far too-small tissue box because their instincts are telling them it would be a good hiding spot for a mouse. There’s also an interesting thing many cats do- they will sit in the illusion of a box.  Put some tape on the ground in an enclosed circle or square, and your cat might just go sit in the middle of it.  Or maybe you make your bed in the morning, and then set a folded shirt or pair of pants on the blanket only to turn around and find your kitty curled up on top.  There are a few hypotheses as to why this may be.  One is that cats are more farsighted: they can’t see things well up close.  So maybe by just seeing the outline of a ‘box’, they are thinking they are actually inside something that has raised edges.  Additionally, when a cat sits on something, it’s their way of ‘claiming’ it.  Cats always want their environment to smell like them, so a new object that they can claim in as easy a way of sitting on it is very appealing to them.  In the case of clothing, because it smells like their person (you), they’re especially interested in mixing their scent with yours as it helps them feel comfortable and safe. Don’t worry too much if you get that expensive cat tree and your cat seems to ignore it in favor of a box- boxes are an easy, quick enrichment item that cats enjoy and know what to do with right away, but they can get boring over time.  A cat tree is a long-term enrichment investment, and after they get used to it your cat will likely grow to love it.  You can help them enjoy their new thing sooner by leaving treats, catnip, or familiar toys on it or next to it, or using a wand toy to encourage them to play on it.
