Loki was a margay. There is a pretty large size difference between a margay (4 kilos) and an ocelot (14 kilos). There is often intraguild predation and killing (sometimes even for energy gain) within the felid guild. When we release an ocelot, we worry about pumas and jaguars. When we release a margay or an oncilla, we worry primarily about ocelots. It's a tough world. And yes, was the saddest thing that's ever happened to me.
