Which is exactly why I put my foot down when my hubs wanted to get some. He was raised on a farm with cattle and I was warned he tried to keep them all as pets.Yes, I got them to keep the grass down, we have had two years of wet weather here. I thought to grow them on, they were skinny, hairy little fellas when I got them and fill the freezer up when they got bigger. They have grown into big shiny beasts that love a pat and lick my hand when I let them in the front paddock . They will be here until they die of old age, lol. Yeah the eyes got me .
