Last Saturday(19th of July) I came out to my kichen and found a baby Garter crawling on the floor. It make's 13 instead of 12. How it escaped who know's but they do. Put it in a container. The other's are in little plastis cricket tubs. I thought they were quite secure as when i have purchased Garters they come in them.
On monday found one empty but the baby was at the bottom of glass square viv they are in so have orderd more secure plasic containers with firmer lids.
