So my dwarf bunny called milky is twitching his head. Out of nothing he start to twitch and then stops. Sometimes he dont twitch at all and sometimes he twitch more. We dont think it somekind of parasite etc because he started to twitch long time ago. We were at vet and got panacur, but just for one or two uses. We dont want to stress him anymore so please help. He does not seems to be affected in any way, he is happy and all but sometimes he starts to twitch and then stops.
