Just before, I was doing stuff in my back garden and found a snail. It was raining non-stop all day yesterday so no doubt the slugs and snails were moving around on the path behind my house - where people step on them, be it purposely or accidently.Somehow, this little guy has managed to live through whatever happened to his shell (he was probably stepped on on the mentioned path) and made it into my back garden. I have no idea what the hell he was doing out in the sun, with no shell, at 1 in the afternoon, but whatever it was it lead him to me.And me, being the animal lover that I am, can't bring myself to kill him. I have a spark of optimism that he may live, although this is nearly impossible considering that he is without a shell and snails with only minor fractures can die.As far as I can tell, none of his internal organs have been damaged so he may be able to live for a little while longer. I'm hoping his last day(s) (if they are his last days) are good.I really don't know what to do. What do snails even eat? All's I can think of is leaves, and as you can probably tell from the pictures there's loads of food waste in there. It was originally a slug habitat, but my brother didn't put the lid on properly and they all got out. I have two snails, somehow. I don't know where they came from or how they got in. So anybody who knows these things, help would be appreciated.You may be wondering why I have a slug habitat? It was an earthworm habitat, but they all died. I tried several times to make one and they all kept dying. So for my axolotls, I had to make a slug one.Pictures:Small sidenote; if his shell were to regrow back, i'd have to keep him until he dies. The shell will not grow properly.
