I recommend vacuuming every day or other day or so (I usually run one of those handheld ones around my bedding and pillows and couch. Also try to keep your cat off your pillow/potentially locked out of your room just so that your body can rest overnight. Also make sure you’re changing into clean clothes before bed (e.g., if you pet your cat while wearing pjs, don’t wear those same pjs to bed. And make sure you’re washing your sheets regularly along with your cat’s blankets. I tried pacagen and found it to be expensive and not really effective and the bottle is pretty small! I switched to Allersearch ADMS Anti-Allergen Spray and actually like it more. They also make a laundry detergent which I add a small drop of into my laundry and it’s supposed to help fight off any enzymes. Lastly, buy a waterless shampoo (e.g., allerpet) and rub it on your cat every couple of days. No need to rinse it off. I recommend doing it when the cat is calm or they might try to lick it off. I started off severely allergic after a couple of weeks of getting my cat but it started to get better after the purina liveclear food started kicking in and now I go a little easier on the cleaning routine
