After discovering that my aunt had been living in unfavorable conditions due to hoarding before she passed away a few months back, we've made some progress in cleaning up. There were two cats involved, and unfortunately, litter boxes weren't cleaned regularly. We've had professionals come in to remove most of the clutter, which helped with the smell significantly. We're planning to paint and replace the carpet, but I'm anxious about making sure any lingering odors don't return. I'm considering using an ozone machine to help eliminate the smell, but I'm curious if I should call the professionals back in for further assistance at some point.

If the cat urine soaked into the wood subfloor under the carpet, you'll want to treat that with an enzyme cleaner. It’s crucial to break it down, or you risk those odors coming back, especially when it's warm and humid in the summer. Sounds like you've got a lot on your plate, but tackling that subfloor could save you headaches later on!
Definitely keep the cats out of the house while running the ozone machine! It’s important for their safety. Glad to hear the kitties have new loving homes now—that must have been quite a task to capture them!

That's exactly what I’m worried about! We plan to list the house this summer, and I really don’t want to deal with odors when potential buyers come through.
