Me, that is.
After writing the last blog post, it occurred to me that I had a willing, and definitely un-pregnant mog hereabouts. Male cats, like male humans, have nipples of course!
Problem with Theo is he has so much floof, I couldn't actually SEE one to compare. I grabbed him to investigate, but he didn't take too kindly to all that rummaging, and stalked off with his tail swishing in a most annoyed manner. Sorry boy.
Later I accosted him whilst he was asleep, and whilst it did wake him, this time he responded by purring madly and enjoying the tummy rub, so I was, eventually, able to find one. Little, white, and not at all like Indigo's. Later on, I walked into my room to see Sofia snoozing belly up on the bed. And yup, Indigo's are much bigger and much pinker than hers as well.
What with the sickness, (now thankfully at an end) and the amount of food that's been magically disappearing from Indigo's bowl recently, I think we can now safely assume that she's pregnant :)
