So you can imagine the shock on Renee Cook's face when her three-year-old cat Amber produced this cute little critter - who was born with two faces.
Miss Cook, of Amarillo in Texas, said she arrived home from work to find her three-year-old Persian and Calico mix had delivered a litter and was shocked when she discovered the two-faced kitten.
The special needs children's nurse said: "I picked it up and said, 'Oh my goodness, two faces'," she told the Amarillo Globe-News.
"I thought it was dead at first because it was cold. But then it started to wiggle and it kept wiggling and wiggling.
"He has a strong heartbeat and was kind of feisty. So now I'm thinking that it's going to live."
The kitten has two mouths, two noses and four eyes, but just two ears.
Ms Cook got some infant formula from a local hospital to feed the as-yet-unnamed kitten.
As the kitten has two mouths, it cannot nurse from its mother, leaving Ms Cook to fill in as surrogate."It can't nurse, but it will take formula," she said.
The kitten's unusual feature has also shocked the veterinary community which said births of this kind were very rare, and those that were born often didn't survive kitten-hood.
Veterinarian David Hodges said: "You don't see many adult cats like that, so the chances of a long-term survival are pretty slim."
However, two years ago, a cat with two heads was born in Arizona, America.Lil'Bit has not only beaten the odds by surviving but has gone on to live a healthy life.
