It may be that xylitol is totally toxic to them. You can usually buy it at a health food store.
The reason is, it is a 5 carbon sugar that bugs love to ingest. But unfortunately, they don’t have the enzymes needed to break it down!
So they literally die stuffed to the gills!
But be VERY CAREFUL with xylitol. It is EXTREMELY toxic to dogs.
Cats I’m not sure about.
And just so you’re ok with it, humans have no problem.
It is toxic for Kittehs too.
Thanks for the word on xylitol. Note however, that I don’t own a dog, only a (very lazy) cat.
