It’s telling you right on screen. Battery service recommended.
Means the battery’s shot. They don’t last forever.
Google how to replace it yourself, see if you’re up for it. If not, find a service to do it. Doesn’t have to be (probably shouldn’t be) the Apple Store. You’re LOONG out of warranty.

To son proof it, just grab an image of the SD card before he starts mucking with it. Easy to flash back to a known-good starting point.

Lay cat in lap. Grab head and kinda hold/lightly pinch cheeks with left hand. With right hand force your fingers pinching the pill into the back of the throat. Push it as far back as quickly as you can with your pointer finger. Hold him to make sure it gets swallowed.
Apologize and give him a little scratch and kiss.
