I apologise in advance as this is not a particularly pleasant topic but ....
This morning I saw, under Smudge's tail, two tiny yellowish blobs (around the skin of his bottom) which, when he awoke properly, he immediately cleaned himself. I've watched him today, he is behaving perfectly normally, no excessive licking or cleaning, no smell.
I haven't seen it before on any cat we've owned and I wondered if anyone can enlighten me?
