Which Cat Supplies Actually Matter and Which Ones You Can Skip

The supplies that make the biggest difference for your cat's health and behavior

A litter box, litter, food, water, and a place to sleep are the only supplies your cat actually needs to survive. Beyond that, the supplies worth your money are the ones that solve a real problem: scratching posts stop furniture damage, nail clippers prevent overgrown claws, and brushes reduce shedding and mats. Everything else — automatic feeders, cat trees with seven levels, heated beds, puzzle toys — is genuinely optional. Your cat will be fine without them.

The catch is that some optional supplies save you money or time over months and years, while others sit unused. A scratching post costs $20 to $60 and prevents damage to a couch worth hundreds. A cat water fountain costs $30 to $50 and may encourage a cat who doesn't drink enough from a bowl. A brush costs $5 to $15 and prevents matting that leads to expensive grooming or vet visits for skin infections. Those are worth buying. A toy shaped like a fish that your cat ignores is not.

Key Takeaways

• Litter boxes, litter, food, water, and a bed are non-negotiable; everything else depends on your cat's behavior and your situation.
• Scratching posts, nail clippers, and brushes prevent costly damage and health problems, so they pay for themselves.
• Water fountains and automatic feeders are worth considering only if your cat has a specific problem — not drinking enough, or you're away for long stretches.
• Toys, beds, and climbing structures are nice but optional; most cats are entertained by cardboard boxes and paper bags for free.
• Buy the cheapest litter that doesn't track through your house, and the cheapest food your cat will eat without vomiting or diarrhea.

Litter and litter boxes: where to spend and where to save

Buy a litter box that is large enough — at least 1.5 times your cat's length from nose to tail. A box that is too small leads to litter outside the box and cats eliminating elsewhere in your home. Size matters more than price. A basic plastic box costs $10 to $20 and works as well as a $100 enclosed box, as long as it is big enough and you clean it daily.

For litter itself, buy the cheapest option that doesn't track through your house. Tracking — litter stuck to paws and scattered across floors — is the real cost of cheap litter, because you end up buying more and cleaning more often. Clay litter costs less per pound than pine or paper, but tracks more. Pine and paper litter track less and are easier to dispose of, but cost more. Test a small bag of whatever you're considering. If it tracks badly, the money you save on price disappears into extra bags and extra cleaning time.

Litter box liners, deodorizers, and enzyme sprays are optional. A liner makes scooping easier but tears easily and adds cost. Baking soda works as well as commercial deodorizers and costs almost nothing. Enzyme sprays help only if your cat has already eliminated outside the box; they don't prevent it.

Food and water: the basics, and when to upgrade

Buy the cheapest food your cat will eat without vomiting or diarrhea. That is the only rule that matters. Expensive food is not automatically better, and your cat's digestive system is the only honest test. If your cat does well on a $15 bag, that is the right food. If your cat throws up or has loose stools on anything but a $40 bag, that is the right food.

Ceramic or stainless steel bowls are worth the small extra cost over plastic, because plastic can harbor bacteria and some cats develop chin acne from plastic bowls. Bowls cost $3 to $10. Wash them daily.

A water fountain is worth buying only if your cat doesn't drink enough from a regular bowl — a vet can tell you if dehydration is a problem. Cats are drawn to moving water, and a fountain can increase intake. Fountains cost $30 to $80 and require daily cleaning and filter changes, so buy one only if you will actually maintain it. A cat that is well-hydrated from a bowl does not need one.

Scratching posts and nail care: prevention that pays for itself

A scratching post is one of the few optional supplies that genuinely saves money. Cats scratch to mark territory and shed the outer layer of their claws. Without a post, they scratch furniture. A post costs $20 to $60. Repairing or replacing a couch costs hundreds. If your cat scratches furniture, a post is not optional — it is cheaper than the alternative.

Place the post where your cat already scratches, not in a corner you think looks nice. A post in the wrong spot will be ignored. Cardboard scratchers cost $5 to $15 and many cats prefer them to wooden posts. Try a cardboard scratcher first.

Nail clippers cost $5 to $15 and prevent overgrown claws that curl into paw pads and cause pain and infection. Trim every two to three weeks if your cat's claws are clear enough to see the pink quick inside. If you are not comfortable trimming, a vet or groomer charges $10 to $20 per visit. Clippers pay for themselves in one or two uses.

Brushes and grooming tools: what matters depends on your cat's coat

A brush costs $5 to $20 and prevents matting, reduces shedding, and catches health problems early. Long-haired cats need brushing two to three times a week. Short-haired cats need it once a week or less. A cat with mats that are already tight may need professional grooming, which costs $50 to $150 and is more expensive than regular brushing.

A slicker brush works for most long-haired cats. A rubber brush or grooming glove works for short-haired cats and is often easier to use. Buy whichever your cat will tolerate. A brush your cat hates will sit unused.

Nail grinders are optional if you already have clippers that work. They cost $20 to $40 and some cats tolerate them better than clippers, but they are not necessary.

Toys and enrichment: what your cat actually plays with

Most cats are entertained by things that cost nothing: cardboard boxes, paper bags, string, and crumpled paper. Before you buy toys, observe what your cat actually plays with. If your cat ignores store-bought toys but attacks string, buy string toys. If your cat ignores everything, a cardboard box is free.

Wand toys with feathers or string cost $5 to $15 and engage the hunting instinct. They work best when you play with your cat for 10 to 15 minutes a day. A wand toy that sits in a closet is wasted money. Laser pointers are cheap but frustrating for cats because they cannot catch the dot; avoid them.

Puzzle toys and treat-dispensing toys cost $10 to $30 and work only if your cat is motivated by food or play. Some cats ignore them entirely. Buy one only if you know your cat will use it.

Beds, perches, and climbing structures: optional comfort

Cats sleep 12 to 16 hours a day and will sleep anywhere warm and slightly elevated. A bed costs $15 to $50, but your cat may prefer a sunny windowsill, a cardboard box, or your lap. Buy a bed only after you observe where your cat actually sleeps. If your cat sleeps on your bed, a cat bed is unnecessary.

Cat trees and wall-mounted perches cost $30 to $200 and provide climbing and observation space. Cats like height, especially in multi-cat homes or homes with dogs. A tree is worth buying if you have multiple cats or if your cat spends long hours alone and needs stimulation. A single cat in a quiet home may never use it.

Window perches cost $15 to $40 and are worth buying if your cat likes to watch outside. Most cats enjoy window watching, so this is a reasonable purchase if you have a window your cat can access.

Automatic feeders and other convenience items

An automatic feeder costs $30 to $100 and dispenses food on a schedule. They are useful only if you are away for long stretches or if you have multiple cats that need separate portions. A cat that is home with you most of the time does not need one. If you do buy one, test it before you rely on it — some jam or dispense inconsistently.

Self-cleaning litter boxes cost $200 to $500 and malfunction frequently. They are not worth the money unless you have multiple cats and genuinely cannot scoop daily. Even then, they require maintenance and often break down.

Microchip cat doors cost $100 to $300 and prevent other cats from entering your home. They are useful only if you have outdoor or indoor-outdoor cats and neighborhood cats are a problem. An indoor-only cat does not need one.

Frequently Asked Questions

Do I need a cat tree if my cat is indoors?

Only if your cat shows interest in climbing or if you have multiple cats competing for space. A single cat that sleeps on furniture or windowsills does not need one. If you buy a tree, place it near a window so your cat can watch outside while using it.

What's the difference between wet and dry food?

Wet food has more moisture and costs more per serving. Dry food is cheaper and easier to store. Most cats do fine on dry food alone, but some cats don't drink enough water and benefit from wet food's moisture content. Your vet can tell you which is better for your cat's health.

Are expensive cat foods worth the money?

Not necessarily. Your cat's digestion is the only measure that matters. If your cat thrives on a $15 bag, that is the right food. If your cat has digestive problems on cheap food, a more expensive option may help. Price does not equal quality.

Do I need a water fountain if my cat drinks from the toilet?

No. A cat that drinks from the toilet is getting enough water. A fountain is useful only if your cat is not drinking enough, which a vet can assess. If your cat prefers moving water, a fountain may help, but it is not necessary for a hydrated cat.

What should I buy first if I'm getting my first cat?

A litter box, litter, food, water bowl, and a place to sleep. A scratching post is the next priority if you have furniture you want to protect. Everything else can wait until you see what your cat actually needs.
