I bought one of these for my cat because she would never come in from outside when I called her. I would click it before feeding her, as I put her bowl down, and then 1-2 more times while she ate. I did it for a few weeks, then I clicked it while she was inside to call her for her dinner.Now if I'm calling her from outside and she doesn't come, I'll grab the clicker and she comes running right to me. I feed her as soon as she comes home and click it again while she eats.It went through the washer/dryer once, and is still working fine.
