I keep the dry food bowl always full. They do appreciate some milk also. They seemingly patiently watch me finish eating, after which I always leave some bits and pieces for them of whatever I had. I then give it to them on the table. They seem to love any meat, saffron rice, macaroni, and anything with tomato sauce.
Males seem to take a bit longer to reach sexual maturity.
I theorize that the basic underlying chemical structure of these sexually stimulating, response activating aromas must be similar in both cats and humans. OK, so now we have to wait some 9 weeks for the new kittys to arrive. I can usually tell when they are nearing that point by feeling their underside. Mommy usually instinctively knows what to do once they appear. It all depends on the frequency of delivery.
