Essential Cat Supplies for New Cat Owners: What to Buy First

Quick answer

Buy the basics in this order: a litter box and litter, food and water bowls, a scratching post, a carrier, and one or two toys. Then add food and treats once your cat is eating and drinking normally. Start with one brand of cat food and one type of cat litter, and only change them if your cat refuses them or has litter box problems.

A new cat does not need a full pet store aisle. It needs a small, working setup that covers eating, drinking, eliminating, scratching, and hiding. Everything else can wait until you know your cat's habits.

This guide covers the cat essentials worth buying in the first week, the trade-offs between common options, and how to tell when a cheaper or simpler choice is the better one. It focuses on cat supplies you will actually use daily, not the extras that sit in a closet.

Start with the five daily-use cat essentials

Most new cat owner problems trace back to one of five things: the litter box, food, water, scratching, or a safe place to hide. Get these right and the first month is much calmer. A litter box should be easy to reach and easy to scoop, food and water bowls should be separate and washed often, and a scratching post should be tall enough for your cat to stretch fully.

Buy one of each first. Cats are sensitive to change, and a house full of new objects can be overwhelming. Add a second litter box, more toys, or a second scratching surface after you see where your cat actually spends time.

• Place the litter box away from food and water, and keep it on a hard, easy-to-clean floor.
• Use shallow, wide bowls if your cat seems to eat or drink reluctantly.
• Put the scratching post near where your cat already scratches, not in a spare room.

How to choose cat litter without overthinking it

Most cats accept a basic clumping litter, and most owners prefer it because scooping is quick. The trade-off is tracking and dust. Pellet or non-clumping litters track less but need more frequent full changes and do not form scoopable clumps. If you have a kitten, check the bag for age guidance, since some litters are not intended for very young cats.

Buy the smallest bag your cat will use in about two weeks for your first purchase. If your cat uses it consistently, size up. If your cat avoids the box, stops covering, or eliminates elsewhere, switch litter before you assume a behavior problem. Change litter gradually by mixing the old and new over about a week.

• One box per cat plus one is the common starting rule, but one box is fine for a single cat in a small home.
• Scoop daily and do a full change on the schedule printed on the bag.
• If you switch litter, keep the box in the same spot so only one thing changes at a time.

Cat food: pick a life stage, then stay consistent

The most useful label detail on cat food is the life stage, such as kitten, adult, or all life stages. Match it to your cat first, then decide between dry and canned. Canned food adds moisture, which is helpful for cats that drink little water. Dry food is easier to leave out and usually costs less per meal. Many owners feed both.

Do not buy a large bag or case of a new food. Buy a small amount, transition slowly over about a week by mixing increasing amounts of the new food with the old, and watch for vomiting, diarrhea, or refusal. If your cat has a diagnosed condition, follow your veterinarian's recommendation rather than a general guide.

• Keep the food your cat came with on hand for the first week, even if you plan to switch.
• Feed on a schedule rather than free-feeding if you need to monitor how much your cat eats.
• Store dry food sealed and use it within the time frame on the bag.

Treats, toys, and supplies that earn their place

Treats are useful for training and for building trust with a shy cat, but they should stay a small part of the daily diet. Dental treats are a practical choice because they do double duty, but they do not replace brushing or veterinary dental care. For toys, a wand toy and a small kicker or ball cover most cats' play needs; you can add more once you know what your cat chases.

Skip the automatic feeders, water fountains, and large toy collections at first. They are not wasted purchases, but they solve problems you may not have. Buy them after you notice a specific need, such as a cat that will not drink from a bowl or one that needs entertainment while you are at work.

• Put treats in a puzzle toy to slow down fast eaters and add enrichment.
• Rotate toys instead of leaving all of them out, so play stays interesting.
• Check treat bags for feeding guidelines based on your cat's weight.

What you can safely delay

You do not need a bed, a second scratching post, or a full grooming kit on day one. Cats often choose their own sleeping spots, and many prefer a folded blanket or a cardboard box over a purchased bed. Grooming tools depend on coat length, which you can assess once your cat settles in.

The one item worth buying early even if you delay everything else is a carrier. You will need it for the first veterinary visit, and getting your cat comfortable with it before that appointment makes the trip easier for both of you. Leave it out with a soft towel inside so it becomes a normal object in the house.

• Wait on beds and grooming tools until you see your cat's preferences.
• Buy a carrier before the first vet visit, not the morning of.
• Add a second litter box or scratching post only if you see a specific problem.

Decision rules for new cat owners

• Litter: clumping or not: Choose clumping litter if you want fast daily scooping and your cat is an adult. Choose pellets or non-clumping litter if tracking and dust are your main concerns, and accept more frequent full changes. Buy the smallest bag first and switch only if your cat avoids the box.
• Food: dry, canned, or both: Choose canned if your cat drinks little water or you want higher moisture. Choose dry if cost per meal and easy feeding matter most. Choose both if you want the convenience of dry with added moisture from canned. Match the life stage first, then transition slowly over about a week.
• Treats: everyday or dental: Choose a dental treat like Greenies if you want one product for rewards and teeth. Choose a plain training treat if you are doing frequent reward-based training and need small, low-calorie pieces. Keep treats a small share of daily calories and check the bag for weight-based guidance.
• When to add a second item: Add a second litter box, scratching post, or water bowl only after you see a specific problem, such as avoidance, competition, or a cat that will not use a shared station. Solve the observed problem instead of pre-buying for problems you do not have.

Product facts that help you decide

• Greenies Oven Roasted Chicken Flavor Cat Treat 4.6 OZ: These crunchy dental treats are made with natural ingredients, including essential vitamins, and are designed to help clean teeth, reduce tartar buildup, and freshen breath. If you want one treat that also supports dental care, this covers both jobs, which is more practical than buying separate training treats and dental chews.
• Oxbow Animal Health Essentials Adult Guinea Pig Food 5 LB: This formula is built on high-fiber Oxbow Western Timothy hay with stabilized Vitamin C and prebiotics. It is a useful reminder that small animal food is species-specific. If you are setting up a home for more than one pet, do not assume cat food or a generic small animal mix fits a guinea pig.
• Aquarium Pharmaceuticals Quick Start 8 OZ: This product uses a nitrifying bacteria formula intended to eliminate ammonia in aquariums. If your new cat setup includes a fish tank, this is a separate purchase from cat supplies and worth planning for before you add fish.

Who this starter list fits

Best for

• First-time cat owners setting up a home before or right after adoption
• Households adding one adult cat and wanting a simple, low-waste starter setup
• Owners who want to buy cat essentials in one trip and add extras later

Not for

• Owners of a cat with a diagnosed medical or dental condition, who should follow veterinary guidance first
• Homes with multiple cats that already need extra litter boxes and feeding stations
• Kitten owners who need age-specific food and litter guidance beyond a general starter list

Buy the daily-use cat essentials first, keep the first food and litter consistent, and add the rest once you know your cat's habits. That approach costs less up front and avoids the most common new cat owner mistakes.
