You could also leave instructions, just like you would for a cat:
- water N times per day, use this cup to this measure.
- check the soil; if it's moist, do/don't water
(don't use these instructions, I have no clue about plants :))
You're right -- the cats themselves are pretty durable (other than my ancient 18 year old Cat A). For me, the instructions are less for the cats themselves, as it is preventing the mess they will make at times.
- Refill all four water containers
- Give them large, heavy dishes full of water because Cat A likes to Knock Shit Over to see if there's water in there. (My hardwood floor has a damaged section because of this: OK if cleaned up fast, not OK if left over the weekend in hot weather.)
- Mix in treats so that cat A eats all of her food
- Cats B and C like to eat Cat A's food, so feed her in a separate room, then open the door 5 minutes later.
Have you experimented with different brands for Cat A? Mixing in treats seems like the least healthy option long term. I've had good success with Applaws.
