The first 12 weeks with your new kitten

A week-by-week guide for your new kitten's first 12 weeks at home. Kittens grow fast — small wins early pay off for a decade or more.

Week 1

A safe small world

Adoption day onwards

  • Use a covered carrier as a familiar safe space.

Milestones to watch for

  • Eats and uses the litter box reliably.

Things you'll want this week

  • Two low-sided litter trays — One in their starter room, one closer to where they will live long-term.
  • Scratching post tall enough for an adult cat to stretch up
  • Soft-sided carrier
  • Two ceramic or stainless food/water dishes
Discuss with your vet:
  • Schedule a first wellness exam within the first week.
