Here's another thing on the story:
"A two-faced tabby kitten was born in Grove City, Ohio, USA on 12th July, 2006 to a cat owned by the Roberts family. Called Tiger, the other 2 kittens in the litter are normal. Though born in the morning, the kitten did not start nursing until the afternoon and is unlikely to survive for long. It has two muzzles, 2 mouths that mew in unison and 4 eyes. On Saturday July 16th, the kitten apparently vanished from its Grove City home. It had been bottle-fed, due to being unable to suckle from the mother, and had last been seen just after Friday midnight. When checked at 4 a.m. it was not in the bed with the mother (a newborn kitten should have been fed every 2 hours, 4 hours between feeds is too long). There was no sign of the kitten and the family believed it was stolen as one of their doors was unlocked, however their dog did not raise the alarm. The most likely explanation is that the malformed kitten was dying and the mother ate it - this is a normal, natural thing for a mother cat to do."- for copyright see link below or
