Just a little story here. My cat got into my grow room during the first week. I usually make sure the doors are closed, but I left it open one day. I had three seedlings in cups. When I returned one cup was empty. I looked and next to the cup, lying on the floor was my poor seedling. As if surgically removed, the root and all. Instead of throwing it away I replanted it, and continued giving it water and light. I am pleased to say it is growing just as well as it's friends. The cat did get his little ass torn and now is frightfully afraid to come anywhere near that space!
