Question about flower pot burial

Hello all! I’m new to this, and i’ve just buried a few rats that were my pets about a week ago, and i’m just wondering if it’s possible to over water the pots?

They’re all in separate mesh laundry bags, all intact (i couldn’t bear the thought of de-fleshing my own pets 🥲), and in a good size pots with i think appropriate soil on top and on the bottom with drainage holes. I know if you don’t water them enough they mummify, but is there a con to potentially over watering?

Thank you for any and all advice! ☺️
