Being concerned about secondary pooisoning, I am very careful about what I use. I was using Sluggo. It says right on the bag that it is safe. Read the fine print, it is only safe if scattered very very sparsley. Most people who have a problem pour it on heavy and do not bother to read the fine print. I have chickens, 3 very large chickens pecked through a sealed bag and ate sluggo. Of course they shouldn't have been eating it, The Sluggo people tell me "well,they shouldn't have been eating it. They couldn't have eaten more than 1/4 to 1/2 cup each when I noticed them. They all bloated up horribly, one died the next day, the 2nd, the next week and the 3rd stayed bloated up and suffering for 4 weeks before dying. I kept thinking I could save her and was trying. So I wonder just how many Sluggo pellets a lizard or small bird would have to eat before it killed them. I no longer put it out where birds can get to it. I no longer consider it safe around small pets or small humans either. Carolyn in Los Gatos, CA
