I'll give it a try. Thanks!We don't have issues with snails but do periodically have issues with slugs. I've had the best luck with placing the bowl the kitties eat from inside a slightly larger bowl (I use a pie pan because the fit's perfect for our bowls) and fill that larger bowl with a thin layer of salt, then place the food bowl on top of the salt. Easy, cheap, and effective without pesticides, etc near their food.
We also - as it warms up - have had issues with ants too. When those start being an issue, we put water in the larger bowl. I've never combined the two (to make salt water) - but if you have trouble with both it'd be worth a try!
