We Moved last week now Coco is Coughing and the other cats have runny eyes

She Is Coughing and her Asthma is acting up. I just chase her around with a inhaler and she blocked me. I do not think she got the med. she moved after I sprayed it. Meeko has a runny eye but ever since she was a kitten she gets them. I noticed Oreo and Sasha have them also. Do you thnk its because we turned the A/C that had not been used in months? I have a sore throat also.

DID you make sure there is a NEW air filter prior to starting??

Omg my Husband just pulled it out and its gross. We will get a new one tomorrow.

Did you change the filter of the A/C before you turned it on. If not, that's probably the reason you all are sick.

We have not changed it. It was left running before we moved in. I bet that is why my asthma is acting up and the Cats have problems.
