My cat was exposed to mold. What health symptoms should I watch for?

Question

My cats have been exposed to Aspergillus & Penicillium in our home for 3 months. We found out only recently, when it sent us (humans) to the ER & are moving this week. They show some symptoms of aspergillosis, fungal toxicity, etc. but vet we saw dismissed them as symptoms of anxiety. Questions: 1. What health issues could the exposure cause? 2. What tests should be conducted? 3. Is 3 months considered long term/serious? Our cats are otherwise pretty healthy. 4. What can I lookout for? Thanks! Pet's info: Cat | Mixed Breed | Male | neutered | 11 years and 3 months old | 10 lbs

Cats are pretty resistant to aspergillosis so you probably don’t have to worry. Nasal aspergillosis causes nasal discharge, enlarged lymph nodes and lethargy/decreased appetite. Systemic aspergillosis really only occurs in immunocompromised cats so if your cats are healthy there is minimal concern. Systemic/disseminated aspergillosis causes decreased appetite, lethargy, GI signs, and fever. Cats are typically very sick with either form. Aspergillosis is everywhere in the environment so 3 months of potential exposure wouldn’t be too concerning - they may be exposed again at some point. Testing is difficult for the same reason and ultimately a CT scan, scoping and biopsy is usually needed for diagnosis. I would simply watch for thick nasal discharge and contact your vet if noted.
