We have three cats- two neutered toms and a spayed queen. The younger of the three cats is a real grub- he likes to play in the compost heap, and is a phenominal hunter. The issue is, he only ever washes his face, paws, 'bits' and tail! His rear legs are filthy- Smudge, the queen, and 'top cat' of the house often pins him down and licks him, though whether this is because she's sick of the grubby boycat, or if it's just a queen thing, I don't know. Is it possible, do you think that he's never been taught? Or that he just doesn't care?!
