Cats can climb on top of sofas, window ledges, onto old tv's etc. Not sure passives with pet safe are ok for cats - they just project the beams higher.

Pure passives are a PITA if you have cats, try and get dual technology ones, even those will probably need masking but should be less prone to false alarms.

Unless your cat(s) stay on the floor nothing will work I'm afraid.

The petsafe ones are in effect desensitised a little so that it takes a fairly large body to trigger them. Unfortunately a small body a bit closer will also do the job.

Dual technology ones are intended to cope with adverse conditions such as sunlight, warm air from radiators, flapping curtains, washing machines and the like. Great for minimising false alarms but absolutely no benefit for avoiding cat triggering.

Best possibility is to restrict the cat to a single room where it can't get anywhere near the sensor. Use a petsafe one for that room and set it so that the beams don't reach near the floor. If you know how, set the PIR so that it needs to count say 3 pulses before triggering too. Better still keep one room where you don't mind not having a sensor at all or programming it to omit when the cat is at home.

Actually that's the 2nd best possibility. Best is to shut the cat outside. I have a cat and I keep it in the utility room which doesn't have a PIR.

HTH.

As above, you will have fa's with a cat, especially a free roaming/jumping one. best bet it to limit to one room without trap protection, usual place is kitchens.
