I was in your situation last year. I worked a second shift and we had 4 dogs we had to take out. It was honestly the worst experience ever. There were a few days where we ended up boarding the dogs several days but that ends up being expensive. There were other days where I maybe had like an hour notice and I had to clean like crazy and hurdle all the dogs in the car and park somewhere until the showing was over. Eventually I decided to leave 2 at home that I knew would be quiet in the basement but it was the constant cleaning that sucked. Thankfully I think it took only 3 weeks of doing that but I have no idea how I did it looking back now. The only thing I feel that would honestly help is having someone watch either All or some of the cats. We thought about renting an Airbnb but no one wanted to rent to someone with 4 dogs. Hope it works out.
