Essential cat gear boils down to five things: a litter box your cat will actually use, food and water they can reach easily, something to scratch that isn’t your couch, somewhere to climb or perch, and a safe way to travel. Everything else is a nice-to-have — genuinely nice, but optional.
What does a cat actually need, gear-wise?
It’s easy to end up buying based on what looks good in photos rather than what solves a real problem. Before you buy anything, it helps to separate gear into two buckets: things that affect your cat’s daily wellbeing (litter, food, water, safe travel) and things that improve quality of life but aren’t strictly necessary (elaborate cat trees, novelty toys, matching decor). Start with the first bucket, get it right for your specific situation — one cat or five, 900 square feet or a house with a yard, an eight-week-old kitten or a fifteen-year-old senior — and layer in the rest as you go.
Below, we’ve broken down each category with the specific things that change the calculation: multiple cats, big cats, small spaces, and older cats. For our in-depth, ranked product picks in each category, follow the links through to our buying guides.
What litter box setup do you actually need?
This is the highest-stakes decision in cat gear, because a litter box your cat dislikes leads directly to accidents elsewhere in the house. For most single-cat households, a well-sized standard box is genuinely fine. Where an automatic or self-cleaning litter box earns its (considerably higher) price is multi-cat homes, where manual scooping frequency becomes a real chore, and situations where odor control matters more than usual — small apartments, shared walls, limited ventilation. Large and heavy cats need to check weight limits and entry size carefully; not every automatic box is built for a 15+ lb Maine Coon. See our full breakdown: Best Automatic & Self-Cleaning Litter Boxes.
Do you need a special litter mat?
A good litter mat isn’t glamorous, but it solves a genuinely annoying problem: litter tracked across your floors. For multi-cat households or homes with long-haired breeds, a larger, deeper-textured trapping mat pays for itself quickly. For a single short-haired cat in a low-traffic spot, a basic mat is usually enough. (Our dedicated litter mat guide is in progress — check back soon.)
Is a water fountain worth it for cats?
Cats are notoriously under-hydrated compared to dogs, partly because many of them just don’t love drinking from a still bowl. A circulating fountain encourages more frequent drinking for a lot of cats, which matters for urinary and kidney health over the long run — though it’s genuinely not necessary for every cat, and some ignore fountains entirely in favor of the bathroom sink. Multi-cat homes benefit from a larger-capacity model so it isn’t refilled constantly. (Our fountain buying guide is in progress.)
What should you look for in a scratcher or scratching post?
Scratching is a physical need, not a bad habit — cats scratch to maintain their claws and mark territory, and they’ll do it on your furniture if nothing better is available. The material matters more than the shape: sisal rope and sisal fabric hold up far longer than carpet-wrapped posts. Height matters too, especially for cats that like to stretch fully upright. (Our scratcher buying guide is in progress.)
Do you need an automatic feeder?
Automatic feeders solve two problems: portion control for cats prone to overeating, and reliable feeding when your schedule is unpredictable. They’re most valuable for multi-cat homes where one cat tends to steal another’s food, and for anyone who’s regularly out of the house at feeding time. For a single cat with a consistent routine and no weight issues, a feeder is a convenience, not a necessity. (Our automatic feeder buying guide is in progress.)
Does every cat need a cat tree?
Not strictly — but vertical space genuinely improves a cat’s quality of life, especially in multi-cat homes where climbing lets less-confident cats get away from more assertive ones. Large-breed cats need a tree rated for their weight, with wide, stable platforms; a tree built for a average-sized cat can wobble dangerously under a 15+ lb frame. In small apartments, a tall, narrow tree or wall-mounted shelving often beats a wide floor unit. (Our cat tree buying guide is in progress.)
What carrier should you buy for vet visits and travel?
A carrier is safety equipment, not an accessory — you’ll need one for vet visits at minimum, and a bad one makes an already-stressful trip worse. Hard-sided carriers with top-loading access are generally easier to get an anxious cat into; airline travel has its own approved-dimension requirements if you fly. For multi-cat households, consider whether you need more than one carrier for simultaneous vet trips. (Our carrier buying guide is in progress.)
What’s different for multi-cat households?
Almost everything scales differently with multiple cats. Litter boxes need more capacity and faster cleaning cycles (or more boxes, full stop). Feeders need to prevent one cat from eating another’s portion. Water and climbing space need enough spots that cats aren’t competing for access. If you’re building out gear for a multi-cat home, we’ve flagged the multi-cat-specific picks in every buying guide we publish.
What’s different in a small apartment?
Footprint and odor control move to the top of the priority list. Vertical gear (tall scratchers, wall shelving, narrow cat trees) helps you avoid sacrificing floor space. For litter boxes specifically, ventilation and odor control matter more than they would in a larger home with more air circulation.
What’s different for a senior cat?
Mobility is the main thing to plan around. Lower-entry litter boxes, ramps to favorite perches, and easier-access food and water stations all matter more as cats age into arthritis or reduced mobility. This is also general information, not veterinary guidance — if you’re noticing new mobility issues in an older cat, it’s worth a vet visit rather than a gear purchase alone.
Frequently asked questions about cat gear
How many litter boxes do I actually need?
The common rule of thumb from veterinary behaviorists is one litter box per cat, plus one extra — so two cats means three boxes. Homes with multiple floors generally need at least one box per floor regardless of cat count.
What’s the single most important thing to buy first?
A litter box your cat will actually use, sized and placed correctly, plus a reliable food and water setup. Everything else can wait.
Is automatic gear safe for kittens or small cats?
Not always by default. Most automatic litter boxes and feeders have a minimum weight requirement, both for safety and so the sensors work correctly. Always check the specific product’s minimum weight before using it with a kitten or a notably small adult cat.
How much does it cost to properly outfit a new cat?
It varies enormously by category and how automated you go. A basic setup (manual litter box, bowls, a modest scratcher and carrier) can run in the budget tier across the board. Adding automatic litter boxes or feeders shifts individual categories into the mid-to-premium tier — we use price bands rather than exact figures in every guide, since prices move.
Do I need to buy everything at once?
No. Litter, food, water, and a carrier are the immediate needs. Scratchers, trees, fountains, and automation can follow once you know your cat’s specific habits and preferences.
What cat gear is genuinely optional?
Elaborate multi-tier cat trees when a simple perch would do, premium fountains for a cat that’s happy with a bowl, and most “cat furniture” marketed on looks rather than function. None of it is wrong to buy — it’s just optional, which is different from essential.
