As the subject implies, BuggersMoggy is a little on the manky / stinky side. He grooms often but a combination of building work and fine weather means he can dust-bathe at his leisure so his white fur perpetually looked yellow / brown.
Add to that the suncream on his ears (which he immediately aims to coat in dirt) and he starts to look really scruffy. He is currently beyond cat wipes...
We brush him every few days but in between he looks like a kitty tearaway with his large size and fighter's ears.
TBH I don't think it's a problem, but worry that I should as neighbours have started to ask about him (again). I worry that neighbours will think he's neglected 
as we had slightly 'over-invested' neighbours in the past that we had to reassure.
Would a scruffy cat bother you? He grooms regularly - no issues there - just he's so daft he goes and rolls in the freshly dug soil immediately thereafter....
He is much loved and fussed over (daily Encore for a start), but I don't want the neighbours at the door again nor to have missed something. We did bathe / shower him before (concrete on paws) but none involved are keen to repeat that....
