Hey this may seem like a dumb question and sorry if it is but how can I tell if a cat is malnourished? I see this super friendly one on walks sometimes always in the same area hunting something. They always are super vocal and brush against me. And they don't look any worse or better between times I see them but I have noticed more matted fur between sightings still very little though. I brought treats and I know some cats will act like they've never been fed in months right after feeding them 10 minutes prior, but they would eat the 5 treats in the span of basically a second and that also worries me. I know they belong to someone at least once upon a time because they have a tattoo but the bugger can't sit still for more than half a second for me to check what it says so I can call the local humane society.
This is the cat in question
