I understand some scientists would say this is sentimental or not objective in studying animal behaviour if we accredit or bond with our study species.

I disagree mainly due to two reasons: 1) being friends with and working professionally with non-human animals are two things – one shall learn to differentiate the two in different contexts (some non-human animals are not that dumb – they study your behavioural pattern while you are study theirs, and thus, they know when to do their job); 2) without them, without ‘success’ (productivity measures that are defined by science community).

So here are **My best buddies** picture7
