We all know how frustrating it can be living with a cat who scratches up couches, clothes, and even walls. It’s no fun living with kitties who use their claws as weapons of mass destruction.
But not every cat is a destructive scratcher, though absolutely every cat is a scratcher at heart. Why cats all love (and need!) to scratch comes down to a number of incredibly powerful benefits cats get out of the act of scratching to their hearts’ content (though again, hopefully not on any human furniture!).
These benefits are the reason why, if you ever do take the time to train a cat to stop scratching destructively (click here for the how-to), it’s important to have a slew of objects you’re happy to let your cat scratch on as alternatives to the human furniture they’re used to taking their claws to.
You don’t want your cat to stop scratching altogether – it’s a biologically ingrained behaviour that’s healthy for them to engage in, and with so many benefits, it’d be detrimental for them to stop. You just want them to re-locate their scratching someplace you’re happy for it to take place.
Scratching posts are a fairly obvious way to go in terms of cat scratch-approved objects, but if you already have one and want more variety for your cat, you may want to try cardboard cat scratchers or small cat trees instead.
Happy to go big if it means your cat will finally leave the sofa alone? Try a massive cat jungle gym, or if you’re in an apartment, a thin cat tower or a floor-to-ceiling type instead. There are plenty of inexpensive cat towers out there as well – so even if you’ve got a tight budget, these days you do luckily still have plenty of options. Human objects like rugs and carpets also work if you can’t stand the look of too much cat furniture.
A scratch-approved object or two in every room your cat spends time in is ideal, so when kitty does get the itch to scratch, your human furniture isn’t the only scratchable object in the vicinity. One way or another, a cat’s gotta do what a cat’s gotta do. Here’s why scratching is part of the deal when it comes to cohabiting with felines…
Why Cats Scratch: 7 Biological Benefits to Feline Scratching Behaviour
1. Scratching helps cats remove the outer shell of their nails – something like natural nail cutting.
Ever seen thin, crescent moon shaped nails on the floor beside your cat’s scratching post? Whether or not you knew it – what you discovered were your cat’s outer nail shells, not your cat’s nails themselves.
It’s a little bit similar to how snakes shed their skin – which is a very cool process to watch by the way (here are some pictures of my old pet ball python shedding in case you’re curious!). Under the old, outer shell of a cat’s nails there’s a new, healthy full-grown sharp nail, just like underneath a snake’s old paper-thin upper layer, there’s a gorgeous smooth, perfectly formed skin beneath waiting to have its turn out in the sun.
Cats don’t have a way to cut their nails, so it makes sense they’ve evolved in such a way that helps them get a sort of nail trimming job done. And that remember how I said the perfectly formed, healthy new nail beneath is sharp? Well, that’s the next benefit:
2. Removing the outer nail shell exposes a new, sharp under layer – so scratching helps cats keep their claws sharp.
Cats don’t technically scratch to sharpen their claws – after all, it’s not like there are any emery board types of surfaces commonly found outdoors. But scratching does help them get their claws back to being sharp since that new, healthy nail beneath has a nice, fine tip.
Sharp nails are ever-so-important for cats, who use their nails to dig into wood and other materials when they’re trying to climb up to difficult-to-jump-to locations. Cats can jump very high, about 5 or 6 times their body length, but their ability to claw their way up things like tree trunks and fences also comes in incredibly handy.
You probably didn’t need me to mention it, but cats also use their nails as weapons when they hunt, allowing them to catch and hold onto prey. Without their sharp nails, it’d be difficult for a cat to survive in the wild. So scratching indirectly helps them survive since it directly helps them to keep their claws sharp, which helps them climb after and keep a tight grip on their prey.
3. Cats scratch to scent mark their territory.
In my article about why cats knead, I spoke about the fact that cats have scent glands in their paws. By kneading, they release their smell onto the object they’re kneading, and with this scent, mark their territory.
Cat scratching also releases a feline’s scent onto the scratched object, thus the act also helps them mark their territory. Scratching has an additional benefit to marking territory that kneading doesn’t quite have, and that’s the following…
4. Scratching helps cats visually mark their territory.
Ever seen the way a piece of wood looks after it’s been scratched up by a kitty cat? It’s pretty obvious a cat’s been there – not just to us, but to other cats and likely other animals as well.
If a cat scratches a tree or anything else really in the wilderness, it’s fairly obvious to other cats that come across those scratches that another cat has been there. Visually marking territory by scratching is thus yet another huge reason why biologically, cats are born with a never-ending itch to scratch.
5. The behaviour of scratching helps cats stretch out their body.
If you’ve ever watched your cat scratch on a post before, you’ve likely noticed your cat doesn’t just place his or her claws along the top and drag. There’s a heck of a lot of movement going on throughout the entirety of a cat’s body before the scratching takes place – a lot of stretching that is.
It seems that scratching is more of a full-body experience, again, a bit similar to kneading.
6. Since stretching is involved in scratching, it’s a highly effective muscle relaxing process.
Yet another commonality with cat kneading, which also involves stretching. You likely know to stretch your muscles before and after exercise, and even without being told, you probably institutionally sometimes stretch out your arms with a yawn when you first wake up after a long sleep. Stretching works the same way for cats, increasing blood flow to muscles, increasing flexibility, range of motion, and even…
7. Scratching acts as a stress relief mechanism for cats.
Stretching in and of itself, even for humans, is a powerful stress-relieving mechanism. Scratching, including stretching as part of the feline scratch ritual, must be enormously helpful in this department for our feline friends. My guess is it goes a long way in calming cats down, keeping their stress levels low, and a good chunk of anxiety at bay.
While I’m not sure if much research has been done on the topic, I’d venture to guess that a cat who isn’t able to engage in the act of stretch-scratching is likely going to end up being a pretty stressed out kitty. So keep your feline scratching (again, the right objects!) – it should go a long way keeping your cat content.
Cat Already Scratched Up the Sofa or Walls?
If you’ve come here out of frustration trying to figure out just why cats can be so viscous to human homes and furniture – say because your kitty’s already scratched up your favourite sofa, rug, or even your doors or walls; don’t sweat it.
Besides proactive measures I mentioned in the intro of this post, you can also protect these all-too-well-loved spots from further damage by installing furniture scratch protectors: like clear cat scratch guards that cats can’t get their nails through or couch cat scratcher posts & mats that cover up damage.
Cat did a really big number on a large part of the couch? You don’t need to replace the whole thing, a couch protector cover should do the trick saving your sofa from further damage or making an old sofa look pretty darn close to new again. Life with cats is a whole lot easier with all the options we have available these days!
Your Thoughts on Feline Benefits Reaped from Scratching?
What do you think about cat scratching? Did you learn about any benefits that you didn’t think about before here?
Did you know the crescent-moon shaped nail that a cat lets off is the outer shell of a cat’s nail that needs to be shed to reveal a healthy, sharp nail below it? Do you remember what you first thought these little outer layers of nails were when you first saw them?
Do you feel your cat uses scratching a lot as a stress relieving mechanism? Do you think cats who can’t scratch probably get a little anxious without the ability to engage in this naturally ingrained behaviour?
Can you think of any other ways cats benefit from scratching objects?
