yes that does indeed say happycow. so. there have been A TON of studies on cows and grooming. the general summary: cows really like to be clean; they’re MUCH happier that way. if you don’t provide them a brush or something like that, they’ll use walls or fences to scratch against, possibly hurting themselves in the process.
but more to the point grooming is a way they calm themselves down, too. similar studies have found that it’s the first thing they do after being freed when they’ve been restrained.
which leads to brushes like the one above, or ones like this (one of my favourite cow photos ever):
cows: anxious and fussy but much happier when able to do self-care. SOUNDS FAMILIAR TO ME
