Cornelius has a habit of moving his water dish. And, even though it's wider at the base, he can tip it. So, I thought of something I could put inside that would not only weigh it down, but alert me that he is low. Summer is upon us, and pets can sometimes get left for the day without water.
I put some of the dollar tree clear rocks in the bottom of his water bowl. They weigh down the bowl and when he is low, I will hear them move around when he is trying to get to the bottom.
Now, before anyone starts warning me about a choking hazard, please don't. Cats don't have the "it's there, I must eat it" mentality that dogs do. Plus I made sure they are too big to even get in his mouth, much less down his throat.
As you can see from the photo, he was a bit, "what is that in my water dish," leery, but only for about 10 seconds, then enjoyed a drink from a bowl that will stay put.
Hope this helps.
