I'll start this thread with a disclaimer: after 20+ years (time flies!) around B's, it's habit to ensure potential toxins are inaccessible. I've eliminated VOC's entirely, make my own cleaners from vinegar, baking soda etc and pesticides/herbicides are banned on my rural property. All of this due to research initiated by the terminal illness of my first B girl. I take the health of my dogs–and my wildlife, land, drinking water--to a whole new level of paranoia
So when my tri youngster got ahold of an apple core I was appalled at myself--in sufficient quantity the seeds are poisonous, but the liver takes a hiteven with small amounts. (I told you: paranoia : p )
Well, by the time I found him he was just swallowing the last of his treat--this boy gobbles food without even tasting it. Which is why I was surprised to find 8 apple seeds at the scene of the crime. It reminds me of my first girl who stole & consumed a massive chocolate chip cookie--but somehow managed to eat AROUND the chocolate chips with surgical precision.
So--do you think B's have instinctive knowledge of natural toxins? From what I've read on this forum they aren't very bright when it comes to artificial sweeteners or mouse bait!
