Help “Mo” the abused and neglected horse

My sister Tamese rescued this poor horse today (her friend rescued its companion). The owner said they couldn’t afford to feed it for two weeks, but obviously it’s been way longer, at least a month. It’s teeth are in terrible so it can not eat hay and is going to need a lot of TLC. It is going to be seen by a vet on Friday. IF you can spare any money at all $5, $10, ANYTHING at all, Senior Pellets are expensive (hay is now $24 a bale). This is probably the 6th horse she has rescued, but it is in, by far, the worst shape. . Thank you ❤️❤️❤️
