Fun fact: OSRS pets (or at least the chaos ele jr) doesn't have any options for other players. It is pretty frustrating having to deal with clan avatars at reset on w48 Burthope so I wonder if its possible for Jagex to do the same with RS3 pets. I recall Alkan briefly bringing this up and I'm sure this would be of interest to many here.
I would love to not only be able to toggle the ability to click on anyone elses familiar/pet/avatar, but to be able to hide them from view entirely. It also bothers me that there is no current option to stop clicking on just other peoples familiars, it also affects your own, which is :l
