Dear Catster reader,

Almost two years ago, we invested numerous resources and rebuilt the Catster community. With new hardware, software and personnel, we did our best to satisfy the many users who shared their thoughts, pictures, questions, and love for and of their pets with us and friends. It was a thriving community with many users. We hoped, however, there would be more like you.

Times and habits have changed and we are sad to announce that the Catster community will be closing down on July 20, 2019.

Catster magazine, and the associated social media sites are NOT shutting down. We encourage you to continue reading the content found in the pages of the magazine and the web sites, commenting through the mechanisms provided and sharing your ideas and comments with us and your fellow readers.

Instructions for accessing pet profiles were shared with everyone in 2017. The instructions can be found elsewhere within the forum. AFTER JULY 20TH, YOU WILL NOT BE ABLE TO ACCESS THIS CONTENT. And, effective immediately, we are no longer able to answer questions about the community.

Thank you for your support and we look forward to serving you through our magazine and website.


is it possible to have identical twin cats>

I got 2 male cats from the same litter. They look exactly alike except one is slightly bigger. Could they be identical twins? Got them neutered yesterday. Both are doing fine.

    It's possible but highly unlikely. The only way to know is to have their DNA was checked. When a cat comes into estrus (heat) & mates, she releases multiple eggs. She releases an egg each time she mates. But usually, she mates with a number of males (unless she's being bred & housed with just one male). That's why kittens can look so different from the same litter. They all have the same mom but each of the kittens could have a different dad. If the same male mates more than once with the female, his sperm can fertilize each egg released. Those kittens will look the same. It's most likely the case with your two kittens. Fraternal twins occur when 2 separate eggs are fertilized at the same time. Identical twins are just ONE fertilized egg dividing but completely splitting into two fetus. It's rare with animals but more common with humans. Twins are simply 2 babies born at the same time. This means a litter of kittens will always be twins, triplets, quads or however many there are.

    I agree with Morgana. I once had a litter of cats up for adoption (I volunteered with a humane organization) and all six cats looked and acted exactly alike. However, when they were adopted out (separately) each developed it's own personality. I think that as your cat grow, they will act less and less like "twins" and more and more like individuals.
