Why Is My Cat Not Using the Litter Box?
Start here, because this is the most important thing on the page: a cat who suddenly stops using the box may have a medical problem, not a behavioral one. Please call us before you do anything else.
Urinary tract infections, bladder inflammation, and other conditions make urination hurt, and the cat, reasonably, blames the box and looks for somewhere that doesn’t sting. This is especially urgent with male cats. A male cat straining in the box, going in and out repeatedly, or crying while producing little or no urine may have a urinary blockage, which is a life-threatening emergency that needs to be seen immediately, day or night.
Once we’ve ruled out a medical cause, most litter box trouble comes down to the setup, and cats are genuinely fussy about it:
- Enough boxes. The rule is one per cat, plus one. Two cats mean three boxes. And they shouldn’t all be lined up in the same spot, since to a cat, that’s really one big bathroom.
- Big enough. Most store-bought boxes are too small. A box should be about one and a half times the length of your cat. Under-bed storage tubs make excellent litter boxes, and nobody has to know.
- Clean enough. Scoop daily. Many cats will simply refuse a dirty box.
- The right feel. Most cats prefer a fine, unscented, clumping litter. The perfumed kind is designed for human noses and often puts cats off.
- The right place. Quiet, easy to reach, and not next to the washing machine that roars to life mid-visit. Older cats need low sides that they can step over without it hurting.
- Covered or open. Cats are split on hoods. Some feel safer, others hate the trapped odor. If your cat is avoiding a covered box, try removing the lid.
A quick but important distinction: a cat who squats and leaves a puddle on the floor has a litter box or medical problem. A cat who backs up to a wall, tail quivering, and leaves a small spray up a vertical surface is doing something different: marking, which is covered below.
Why Is My Cat Spraying or Marking?
Marking isn’t a bathroom act; it’s a message, usually about stress or territory.
A spraying cat is broadcasting into a world that feels unsettled. Common triggers include a new pet or person, a move, a neighborhood cat visible through the window, or tension between cats already in the home. Neutering or spaying reduces or eliminates it in most cats, so that’s the first step if it hasn’t been done.
Beyond that, the fix is to calm the underlying stress rather than punishing the cat, which only adds to it. Clean sprayed spots with an enzymatic cleaner so the scent flag doesn’t reinvite a repeat, block the view of outdoor cats if that’s the trigger, and ask us about synthetic pheromone products, which genuinely help some cats. If marking is persistent, let us take a look, since sometimes it has a medical component too.
Why Does My Cat Scratch the Furniture?
Because scratching isn’t your cat being destructive, it’s a deep need, and the goal is to redirect it rather than stop it.
Cats scratch to keep their claws healthy, to stretch their shoulders and back, and to mark territory with both scent and the visible mark itself. A cat with nowhere appropriate to do that will use your sofa, not out of spite, but because the sofa is there and it works.
- Offer the right posts. Most cats want something tall enough for a full stretch and rock solid, since a wobbly post gets abandoned. Sisal rope and cardboard are usually favorites.
- Put them where the cat wants them. Next to the furniture they’re targeting, or by a favorite sleeping spot, since cats love to scratch on waking. A post hidden in the basement won’t get used.
- Make the good option easy and the bad option less appealing. Reward using the post, and temporarily cover the couch corner or add double-sided tape while the habit shifts.
A note we feel strongly about: declawing is not an extra-large nail trim. It’s the amputation of the last bone of each toe, and it can cause lasting pain and behavioral problems. It’s far better and kinder to work with the scratching instead. We’re glad to talk through humane options, including regular nail trims and nail caps.
Why Is My Cat So Active at 3 a.m.?
Because your cat is wired to hunt at dawn and dusk, and an under-stimulated indoor cat saves up that energy for the least convenient possible moment. Most “problem” energy is really boredom. The cat isn’t misbehaving, it’s under-employed. The answer is to give the predator a job:
- Play with purpose. A couple of ten-minute wand-toy sessions a day, each ending in a “catch” of a toy they can grab, drains the hunting drive productively. A session right before bed helps everyone sleep.
- Feed the hunter. Food puzzles and treat balls turn eating into work, which is exactly how a cat wants it.
- Build up, not just out. Cats live in vertical space. Shelves, cat trees, and window perches turn a small home into a much bigger one and give a nervous cat somewhere safe to survey from.
- Rotate the toys. A toy that vanishes for two weeks comes back new. Cats bore quickly.
Enrichment isn’t a luxury for indoor cats. It’s the difference between a content cat and an anxious, over- or under-eating, occasionally destructive one.
When Should I Talk to a Vet About My Cat's Behavior?
Reach out if:
- Your cat stops using the litter box, or a male cat is straining to urinate. Straining is an emergency.
- Behavior changes suddenly. In cats, a behavior shift is very often the first sign of pain or illness, since they hide both so well. Hiding more, eating less, grooming poorly, or new grumpiness all count.
- Your cat over-grooms to the point of bald patches, which can be stress, allergies, or pain.
- Aggression toward people or other pets appears or worsens.
- A new stress in the household, a move, a new baby, a new pet, has thrown your cat off, and you’d like help easing the transition.
Changes we can explain are easy to dismiss as “just a phase.” In cats especially, they’re worth a call because so often a cat’s body speaks through behavior first.
