New kitten starter kit (UK): what to buy in the first month
A new kitten is less work than a puppy but the right setup matters as much. The two most common cat-owner regrets in year one are buying the wrong carrier and skipping multiple litter trays.

What to look for
- Top-loading hard-shell carrier — easier to load. Will be used for the cat's whole life.
- Two litter trays minimum — one is never enough.
- Stable food and water bowls — wide ceramic, not narrow plastic.
- Scratching post sized for the adult cat.
- Microchip — legally required in England from June 2024 by 20 weeks.
- Vet booked for first check and vaccination plan.
What to avoid
- Soft fabric carriers as the only carrier.
- One small litter tray — guarantees house-soiling problems.
- Lilies in the home — fatal to cats from any contact.
- Cheap plastic food bowls — linked to feline chin acne.
- Letting kittens outside before second vaccination and neutering.

How we chose these
The guide's own experience is that carrier choice and litter tray count are the two most common regrets in a kitten's first year, so those get top billing here over less consequential purchases. Lilies are called out specifically, not just 'toxic plants' generically, because they're fatal to cats from pollen or leaf contact alone, not just ingestion.

Do I need pet insurance for a kitten?
Yes. Most policies have a 14-day exclusion period. Insurance from day one means full cover from day 14.
When can the kitten go outside?
After full vaccination course AND after neutering. Most UK vets recommend 4–5 months minimum.
How many litter trays do I need?
One tray per cat plus one extra. For a single kitten in a single-storey home, two trays minimum.
