Bob & Sue, I hesitate to use the borax cure because our cat goes out into

I was thinking that
1 Cats wouldn't be interested in eating borax and
2 Borax wouldn't be really toxic to mammals anyway.

I did a quick search to see if I was right about the toxicity and found
this:
*** Terrestrial animals: Borax is practically nontoxic to birds and
mammals. It is relatively nontoxic to bees. Relatively high
concentrations of boron compounds are toxic to insects, and borax is
used for insect control in some cases. ***

That information came from he

The big surprise (to me) was that borax is a fungicide. I've known, for
decades, about it being used on ants but never knew it is sold as a
fungicide.
