How Well Does PIR Pet Immunity Work?

I don't have much experience with residential applications, and my boss wants assurances that if he puts a PIR with pet immunity in his house, his 2 small cats will not cause false alarms. The application is within the spec (immunity to 30 lbs) of the product I am looking at (Bosch), but I am hoping someone has the experience to say that pet immunity typically works as advertised, or that mixing motion detectors with cats is asking for trouble.

Thank you!
