Why it matters

DualScan reads your cats' existing microchips, so neighbors' cats and wildlife can't get in. Because it scans on the way out too, you can keep specific cats indoors while others come and go. It stores up to 32 pets.

It fits doors, windows or walls with accessories. The opening is 4 3/4 in high by 5 5/8 in wide, and four AA batteries last up to a year with normal use.

Who it's for, and who should skip it

Good fit if

  • Mixed indoor and outdoor cats
  • Homes with intruder cats
  • Cats on medication curfews

Look elsewhere if

  • Doors too thin for the frame
  • Cats larger than the opening
  • Owners who can't cut the door or wall

Pros and cons

Pros

  • Scans in and out
  • Stores 32 pets
  • Year-long batteries

Cons

  • Small opening
  • Batteries not included
  • Mounting accessories extra

Limitations to weigh

  • Measure your cat's widest point and the door or wall thickness before cutting; check the cut-out size on the maker's template.
  • Confirm your cat's microchip number and standard before buying; a vet or a scanner can read it.
  • Prop the flap open for the first days and reward your cat for using it; most cats learn within a week.
