The kitten has now grown up, and the adopter caught the kitten grooming Mr Quack last night!!
This is the post-grooming picture.
The Quack and his friend!
Flashback: Mr Quack is the terrorist who created havoc in my community last year when he appeared from nowhere and went on a brief reign of terror ("I come, I see, I terrorise."). I caught him, got him neutered and rehomed. The change of environment for him really did him a lot of good. It did US a lot of good too!
