I purchased this for my cat with kidney disease. I used it for a little over two months, but unfortunately, my cat passed away, so I am selling it. It comes with a cooler pack, so I was able to safely feed wet food even in the summer. The timer allows you to set up to 6 feeding times. It's rechargeable, so it's convenient. The instruction manual is included. Uchi no Ko Electric Karikari Machine FR (Fresh) Automatic Feeder Wet Food Cat Dog Timer Automatic Food Dispenser USB Rechargeable, No Batteries Needed
