Advertisement Sorry if this has been covered before, I did do a search and couldn't find what I was looking for. Iv'e heard somewhere on this forum that feeding mice to Tarantulas can cause health issues for the tara from the calcium in the mouse. Is this true? I do NOT feed live mice! But my Smithi will happily eat a pre killed pinky mouse which I find my easier than feeding crickets. He will also eat bits of raw steak and chicken. I do try and feed crickets now and then when I can get them, but where I live its very hard to find a decent supplier of crickets. Anyway my question really is it safe? I know in the wild Taras can and do kill small mice and birds and frogs, but then it was said about the calcium so now Im not sure, can someone offer advice please?
