I live in gated community townhouse. my neighbor got a puppy or kitten not sure. Every day night it keeps howling , meowing type of sound. At first I tried to ignore. But everynight it's irritating it keeps howling whole night. I think they lock the pet in pet box or cage at night. Upon morning the sound ceases. It's happening for last 15 days. It really gives me bad headache, my other neighbor is also irritated with this. Her child not sleeping well. I don't know the neighbor, how to approach? there is no HOA or neighborhood association.
