No doubt, Mammis and snails do not mix. Often times I will come out in the morning to check on stuff and snails are just crawling over the spines like it's no big deal. Try wrapping some thin copper/copper tape around the pots. Snails get shocked when they touch copper. Great deterrent but they can always still fall on from above.

Try put the picture on the Cacti Gallery forum. /David

Opuntia microdasys aka Bunny Ears cactus;).

Stefan thanks for the links, interesting and the flowers are lovely. It says to look after them, they need lots of sun, moisture and fresh air. Well up north where my son lives it would get lots and lots of sun and fresh air but not much moisture, sometimes basically nothing in the summer. So thats probably why it's so messy. I like the monstrosa form better, if I could ever like a cactus lol. Kara yes many of the Opuntia are wreaking havoc in pasture, grazing lands and in National Parks too. Sheep, kangaroos you name it are dying slowly from the spines. So I'm going to check the species name against the "Reportable weeds" list, then ring whoever deals with them. Thanks guy's
