The cats seem to spend quite a bit of time on the porch across the street from my mom and dad, and the porch across the street and one door over. I'll ask my parents about those neighbors to start. My parents won't be able to maintain the responsibility of feeding them regularly. Mom is 80 and has arthritis in her knees and spine. Dad is 84 and is having a knee replacement on Monday. I just don't want any of the cats getting struck by a car.
