Why it matters
The 210 is designed for glass: single or double glazing up to 1 1/4 in thick, and also wooden doors up to the same thickness.
Complete instructions are included; cutting a hole in glass is a job for a glazier.
Who it's for, and who should skip it
Good fit if
- Glass doors
- Patio doors
- Screen doors
Look elsewhere if
- Thick doors

Pros and cons
Pros
- Made for glass
- Also fits wood
- Compact
Cons
- Glazier needed
- Any cat can use it
- 1 1/4 in max
Limitations to weigh
- Have a glazier cut the glass; many units need a new pane made with the hole.
- Prop the flap open for the first days and reward your cat for using it; most cats learn within a week.
- A flap that opens for any cat can let neighbors' cats and wildlife in; selective flaps prevent that.
