This is Pinball - some of you long time blog readers may recognise him from earlier posts. Pinball lives in my study where I work which is why he is usually the cat featured in photos - he is also a much nosier cat than his friend who shares the room with him and far more aggressive.
Now Pinball is NOT pregnant -though he may look fat, Pinball is a boy. Pinball is also, as you might be able to tell, not a starving cat, though he'll often tell me different when he wants food in his bowl.
By all accounts therefore, some people, like this RC member, will tell you that cats which are fed like Pinball, will have lost all their instincts. Being well fed, they will no longer hunt. See post above to see what 'present' Pinball left for me this morning.
