No luck in getting landlords to reply

My girlfriend & I are planning on traveling for a year, working remotely, in 5-6 location across the US. We've reached out to a dozen or so landlords in our first planned stop (Portland, Maine), but have gotten only one response. I filled out my profile, have been sending custom messages, and still cannot get anyone to reply. Does anyone have suggestions on getting responses? A few thoughts:

-We have not used furnish finder before, so we have 0 reviews. I am wondering if these landlords think I'm a bot

-We have a cat, but are only reaching out to places that allow pets. Do landlords prefer dogs over cats?

-We're only looking to do 2 months in each location, is this not a long enough time for people to consider us?

Any tips would be appreciated!
