I have my boy cat on a diet for the next few months because he is starting to get a bit too big in the waist. He tends to eat most of the food each day and my girl cat is shrinking as a result. So now I feed her first and keep him in the bedroom till she is done eating, then he gets to come out and eat the rest of the food. I can’t have one fat cat and one skinny cat because it isn’t honorable for the girl animal to be hungry all the time. Air purifiers in my home keep the air quality fantastic here as we have three cats and I am a bit allergic to them, which is the same as my HVAC tech friend who has two cats in her home that make her sneeze. I have a vacuum cleaner that runs on a timer each afternoon, keeping the floors nice and clean without me having to do anything. I just have to empty the HEPA filter once a afternoon in the thing and it keeps the air quality good by getting all the dust off of the floors. I used to have to vacuum the floors myself all the time and now the robot does the dirty work for me. My main HVAC system also has a HEPA filter to keep the air disinfect and my flu symptoms are a lot better now that the air conditioning is running all the time. It will be a long hot summer time so I am gearing up for it.
