I have a cat named mouse that loves HVAC units.
When my cat was a kitten, we purchased a new window air conditioner for our living room.
At first the loud sounds of the air conditioner scared the kitten, but eventually she came to love the cool breeze that came out of the window air conditioner. A few years later we got a combined heating and air conditioning system installed in our house. When the heater would turn on, it would blow warm air through the air vents on the floor. When we first got the heating system installed, Mouse didn’t know how to react. One day she was sleeping on one of the floor air vents when the heating system kicked on and started blowing warm air through the air vents. Mouse jumped up and ran away because she wasn’t expecting something to come from the air vent. This happened several times before she got used to the heating system. Now that we have had our combined heating and air conditioner system for a few years, Mouse will curl up on the heating vent and take a nap in the warm air. Last week we purchased a small portable space heater to go under our desk in our room. Mouse has come to love the space heater more than the heating vents. She will spend hours just relaxing in front of the space heater. While me and my family do love all of our different kinds of HVAC units, It is pretty clear that our cat loves them more than we do.
