I would normally recommend perimeter protection for rooms with pets, especially for cats.
K Band DT or I prefer a Super Quad PIR. I.E. Honeywell DT7550 or Optex FX50SQ
I haven't used one but I imagine only the casing is different.
Installing them and wiring them correctly!
Ideally they should be on there own zone.
May not even be possible to do this depending on the panel and cabling.
