most new installs use the Visonic Next K9-85 that is suppose to be pet tolerant up to 85 lbs. Now that being said if the pet is moving alot in the area of the sensor then it could still set off the alarm. I would suggest resetting up your sensor for a "pet curtain". By flipping the sensor upside down and moving it from 7 ft on the wall to say 3.5 feet on the wall you create a area where your pet can safely walk but anyone who enter that are can still set off the motion.
