New Cat Owner Checklist UK: Everything You Actually Need

You have made the decision. A cat is coming home. Maybe a kitten from a breeder, maybe a rescue from Cats Protection, maybe a friend's cat that needs rehoming. Whatever the route, the feeling is the same: mild panic that you are not ready.

Good news. You probably need less stuff than you think, and most of what you do need is available at Pets at Home or delivered next day from Amazon. The bad news? Pet shops and online lists will try to sell you a mountain of things your cat does not need, does not want, and will actively ignore.

This is the realistic version. What to buy before your cat arrives, what to do on day one, what the first week and first month actually look like, and what you can safely skip without your cat suffering in the slightest.

Before Your Cat Arrives: The Essentials

Get these sorted at least 48 hours before collection day. Do not leave it to the morning of, because you will forget something and your cat will spend its first hour home while you are at Pets at Home buying a litter tray.

The Non-Negotiables

Strongly Recommended

Day One: Bringing Your Cat Home

The journey home sets the tone. Keep it calm, keep it quiet, and resist the urge to open the carrier every five minutes to reassure them. They do not want reassurance. They want the motion to stop.

The Journey

• Secure the carrier on the back seat with a seatbelt through the handle, or in the footwell
• Cover the carrier with a light blanket to reduce visual stimulation
• No music, no air freshener, no stopping to show friends your new cat
• If the journey is over an hour, offer water in a small clip-on bowl (most cats will refuse, but offer it)

Arriving Home

This is where most new owners make their first mistake. They open the carrier in the living room, expecting the cat to bound out and explore. What actually happens: the cat bolts under the sofa and stays there for six hours while you sit on the floor with treats, questioning your life choices.

Instead, do this:

1. Set up one room as a "safe room." A spare bedroom is ideal. If you do not have one, your bedroom works. Put the litter tray in one corner, food and water in the opposite corner (cats do not like eating near their toilet, which is reasonable), and a bed or blanket somewhere sheltered.
2. Place the carrier in the room, open the door, and walk away. Leave the room. Close the door. Let the cat come out on its own terms. This might take 20 minutes or 4 hours. Both are normal.
3. Check in quietly after an hour. Sit on the floor, speak softly, do not reach for the cat. If they approach, great. If they do not, leave them be.
4. Keep the room as their base for at least 48 hours. Two days minimum before you start opening doors and letting them explore further rooms.

First Night

Your cat will probably not sleep. You might hear scratching, meowing, or general prowling. This is normal. They are mapping their territory, checking exits, and working out whether they are safe. By night two or three, this usually settles. If you are a light sleeper and the cat is in your bedroom, earplugs are a worthwhile investment for the first week.

First Week: Settling In

The first week is about building trust and establishing routine. Cats are creatures of habit. The sooner you establish predictable patterns, the faster they settle.

Feeding Schedule

Feed at the same times every day. Most owners do morning and evening, roughly 12 hours apart. For kittens under 6 months, three or four smaller meals spread through the day. Stick to whatever food the cat was eating before. If you want to switch brands, start mixing in the new food gradually from week two -- 25% new, 75% old, increasing over 7-10 days.

Litter Tray

Scoop at least once a day, twice if you can. A dirty litter tray is the number one reason cats start going outside the tray. If your cat is not using the tray, check three things: is it clean enough, is it in a quiet spot, and is the litter type the same as what they are used to? Most litter tray "problems" are actually human problems.

Vet Registration

Register with a vet within the first week, even if your cat does not need anything immediately. You want to be on their system before an emergency happens at 11pm on a Saturday.

What to sort at the first appointment:

• General health check -- GBP 30-60 depending on the practice
• Microchip check -- confirm it scans correctly and update your details on the database (Petlog, Identibase, or whatever database the chip is registered with)
• Vaccination status -- bring any paperwork from the breeder or rescue. If vaccines are not up to date, book the primary course
• Flea and worm treatment -- vet-strength products like Broadline or Advocate are more effective than pet shop spot-ons. GBP 8-15 per monthly dose
• Neutering -- if not already done, book it. Typically GBP 50-80 for males, GBP 80-150 for females. Most rescues neuter before rehoming. Breeders vary.

Microchip Transfer

This catches more people out than anything else. Your cat is microchipped, but is the chip registered to you? If you got the cat from a breeder, they may have registered it in their name. You need to contact the chip database (the number is on the paperwork) and transfer ownership. This costs GBP 0-15 depending on the database. It is also a legal requirement since June 2024 -- all cats in England must be microchipped and registered to their keeper by 20 weeks old.

Gradual Exploration

After two days in their safe room, start leaving the door open while you are home to supervise. Let the cat explore at their own pace. Do not carry them to different rooms. Some cats will explore the whole house within an hour. Others will stick to two rooms for a week. Both are fine. Close off rooms with hazards (open windows without screens, toxic plants, unsecured heavy items on shelves) until you have cat-proofed them.

First Month: Building Routine

Feeding

By now you should have a solid twice-daily feeding routine. If you are switching food brands, you should be fully transitioned by the end of week three. Weigh portions with a kitchen scale. The feeding guidelines on the packet are a starting point, not gospel -- adjust based on your cat's body condition. An indoor-only cat typically needs 10-15% less than the packet suggests.

Play and Bonding

Two play sessions a day, 10-15 minutes each. Morning and evening works for most cats because it aligns with their natural active periods (dawn and dusk). Wand toys are the best tool for the first month because they let you interact without invading personal space. If your cat is still shy, trail the toy past their hiding spot and let curiosity do the work.

Litter Training

Most cats and kittens arrive already litter-trained. If your kitten is having accidents, it is almost always a location or cleanliness issue, not a training issue. Place the tray in a quiet, accessible spot away from food and high-traffic areas. If you have a multi-storey home, put a tray on each floor for the first month. You can reduce to one later once they have established their preferred spot.

Insurance

Sort this in the first month if you have not already. Lifetime cover is what you want -- it covers conditions for the cat's entire life, not just the first 12 months after diagnosis. Time-limited policies are cheaper but leave you exposed for chronic conditions like kidney disease or diabetes.

Typical costs for lifetime cover in 2026:

• Moggy (mixed breed): GBP 8-20 per month
• Common pedigree (BSH, Ragdoll, Maine Coon): GBP 15-35 per month
• High-risk breed (Bengal, Sphynx): GBP 25-45 per month

Providers worth comparing: Petplan, ManyPets (formerly Bought By Many), Agria, and Waggel. Use a comparison site like GoCompare or MoneySuperMarket, but also get direct quotes -- comparison sites do not always include every provider. [AFFILIATE: Petplan] [AFFILIATE: ManyPets]

Outdoor Access (If Applicable)

If you plan to let your cat outside, do not do it until they have been in your home for at least 3-4 weeks. They need to establish your home as "base" before they start exploring outside, or they may try to return to their previous home. Kittens should not go outside unsupervised until they are neutered, vaccinated, and at least 5-6 months old. A microflap (one that reads your cat's chip) costs GBP 60-150 and prevents every neighbourhood cat from using your kitchen as a buffet. Check prices on Amazon

What You Can Skip

Pet shops and online listicles love to pad out the "essentials" list. Here is what your cat genuinely does not need, at least not right away.

• Cat tree (month one): Nice to have eventually, but not essential in week one. Your cat will not use a 150cm cat tree while it is still hiding behind the sofa. Buy one once they have settled and you can see where they like to perch.
• Automated litter trays: GBP 200-500 for something that frightens most cats with its motor noise. A GBP 5 tray and a scoop work perfectly well.
• Cat grass kits: Some cats love it, many ignore it. Try a GBP 2 pot from Pets at Home before investing in a subscription service.
• GPS trackers: Useful for outdoor cats that roam, but pointless for the first month when your cat should be indoor-only anyway. Consider later if needed.
• Expensive beds: Your cat will sleep wherever it wants, which is usually your pillow, the bathroom sink, or on top of the router. A folded blanket in a cardboard box is genuinely as good as a GBP 40 memory foam cat bed for the first few weeks.
• Clothing or costumes: No. Just no. Your cat does not want to wear a jumper. The exception is a medical recovery suit after surgery, and even then they will resent it.
• Calming treats (over Feliway): The evidence for calming treats is weak. Feliway diffusers have actual clinical studies behind them. Stick with the diffuser for settling-in stress.
• Multiple scratching posts: One is enough for month one. Add more once you know where your cat likes to scratch. Buying three posts and placing them where you think the cat should scratch is a waste if the cat has other ideas.

Total Cost Breakdown: Getting Set Up

These costs are on top of the cat itself. A rescue adoption fee is typically GBP 60-150. A pedigree kitten from a registered breeder runs GBP 800-2,500+ depending on breed. See our full cost breakdown for monthly running costs after the initial setup.
