My beautiful siamese didn't come home a few weeks ago when a big thunderstorm was approaching. He was never outside all night and never missed dinner. He didn't like thunderstorms and I figured he would come home after the storm. He didn't...for 3 weeks! I had almost given up that he would come home when he appeared in the driveway when I came home from work. He was dehydrated and very hungry but overall in pretty good shape. I took him to the vet to be checked and they said he looked okay. He really wants to go out again but I am very nervous about doing that as I don't want to lose him again. He looks purebred but he is not. Some have thought that someone took him and he escaped. Personally I think he looked for cover during the storm and got locked in someplace. I'd love it if he wanted to stay in but he really wants to go out. Any thoughts/advice?
