In my experience, i was about to end the day but my cat decided to sleep on the stairs right in front of my house. This caused me to pass out coz I didn't have a choice. Another problem I see is whenever I try to put hay on the Animal food trays, they keep blocking the space. I have to wait and waste a few minutes. This one is easier to resolve on my own during Spring-Fall as I can just let them out but this is more critical on Winter I think. Is there a way we can make them not 'stay' on the critical areas? Thanks. Hope to get some answers.
