Grew up on wild rabbit and pigeon that dad had trapped. All year round with the veges mum had grown. Don't know if Aussie feral critters were more worm free than what you have or if we just led a worm filled childhood.

I remember a funny story about Arsenic - about 30yrs ago friends of ours owned a Caravan Park - people kept dumping cats there - so Bill being a not sentimental ex soldier - put out bowls of milk laced with Arsenic - the cats got sleeker and healthier. When he asked a vet about it - it turns out small amounts of Arsenic are healthy - but when does small become big is the question. The answer is amount per kilo of weight.
