Approached several horses, right clicked to try to mount them. When looking at them no wording came up. When right clicking, the horse went up on its hind legs but without my character having mounted them.
An ocelot approached me as I was holding raw salmon. Stood right in front of me. Right clicked to feed the ocelot the raw salmon/tame the ocelot. Nothing happened. Held the right button down, made my character try to eat the raw salmon. Ocelot was still stood right in front of me. No "tame" wording came up.
