I got new neighbors this last spring and a couple months later they bought 3 horses. Well I never saw them interact with them. They don't get riden or petted. I asked my husband this last summer if they just ate grass? I really don't know a lot about horses. We do have goats and I assumed they were a like. My husband said yes they will eat the pasture and maybe some pellet, if they give them to them. I saw the horses break down a potty pond gate to get to the water. This winter I never saw any hay, on this 2-3 acre lot, for them to eat. I never saw anyone come out to water them...well they just burried the 2nd horse. The other one was burried a few weeks ago. Now I feel really bad for not listening to my gut feeling. They have the third horse in their barn. I don't know if they are feeding it in there or not. I am just sick to my stomach. I just can't stand this! How can I approach this situation? I don't want to just let it go but I don't want to but in someone elses business, if it is a very innocent happening. What should I do?
