5 Rules for a Kitten

Five things that make the biggest difference in your kitten’s first year — food, company, fleas, litter boxes, and staying indoors.

1) Food

  • Kitten food until 1 year old.
  • Wet food for their whole life. It does not increase dental problems.
  • Aim for under 10% carbohydrate and under 50% fat — see catinfo.org.

2) Cats Are Naturally Solitary

  • A new cat can bring illness into the house.
  • It also adds stress, which is linked to bladder ulcers and blockages.
  • Introduce new cats room by room, not all at once.

3) Fleas

  • Indoor cats still need flea prevention.
  • Fleas come in through window screens and on other pets.
  • Adult fleas are only 5% of the problem — most of it is eggs and larvae in the home.

4) Litter Box

  • One box per cat, plus one spare in a multi-cat home.
  • If the box has a lid, face the opening toward the room.
  • Keep boxes somewhere quiet — not beside the washer or dryer.

5) Keep Cats Indoors

  • Indoor cats live far longer — 12–15 years on average, against 5–7 outdoors.
  • They still need vaccines: viruses travel in on clothes and shoes.
  • Ask us about vaccinating for FeLV.
