Rights of Neighbors and Animals

Asalamu'alykum Wa Rahmatullahi Wa Barakaatuh Dear Shaikh, For quite a while my family have been feeding stray cats in our garden as a means of reward, having listened to many stories about kindness towards animals we thought it could be a means of jannah for us, up until recently we have not had any issues from our neighbors, we have only recently been made aware that these stray cats have been leaving excrement in their gardens. The neighbors have told us to stop feeding them as it is causing them annoyance having to clean the waste. If we stopped feeding them then they would potentially stop coming to the area, although that isn't certain as others might also be feeding them. We were wondering how to tackle this, do we listen to our neighbors and completely stop feeding the cats or do we continue to feed them and continue to gain reward as there is no point stopping as others might also feed them?
