This bowl can’t be flinged as it really stays still and can’t be moved at all. My cat tried and tried and had to give up, the suction element is really good in this particular one. Mine doesn’t use paws to play in the bowl, he enjoys catching water being splash, so if your girl paws on the surface I imagine she would still be able to do this, but if you won’t fill the bowl completely, I imagine the mess will be considerably smaller.Did it help prevent flinging and splashing with paws specifically? Those are my main issues. I also don't think she actually drinks water ever. If it doesn't make her actually drink it may not be worth buying.
If she does it regularly she still gets some water from cleaning herself after playing with it and that may be her main water source now. So taking water from her may be dangerous even if she only drinks the minimal amount. Some wet food are really salty making them thirsty despite water being added (my cats are on wet only too, one still drinks some water occasionally, the other almost never, but on the rare occasions when he does, he needs to have access to it).
