Hello, so my Ollie is a little over 3 months now and sometimes he'll start crying and won't stop. I'm renting right now and my neighbours have one level of the house and I the other with 1 door separating us. One of my neighbours doesn't work so she's home all day and she's kind of noisy so my guess is he wants to see what's going on there. My neighbour has said that sometimes he will sit outside the door and cry almost non stop which breaks my heart but at the same time I don't want my neighbours annoyed. Is there any way to stop this behavior? I've tried ignoring him so that he can learn that he can't always get what he wants when he cries but that hasn't seemed to work. Is it something he'll grow out of? Or is there anything else I can try? I always make sure he has fresh water, enough food, toys, a clean litter box and I always play with him before I leave. I can't seem to find a way to stop it so any help or advice is greatly appreciated. THANKS!!
