They’re adorable. We once had three lookalikes, all males, all named Buckley.
This reminds me of visiting the animal shelter once, and seeing 15 black kittens…I was suddenly struck with the idea that I could have a dozen black cats, and as long as only one or two at a time went outside, I would be not just a Crazy Cat Lady, but a SECRET Crazy Cat Lady. One has to have goals, right?
At work, we draw on the insides of their ears with sharpies if we need to tell them apart. We also use collars- two collars is good because it’s less likely that they’ll take them off.
Other than that, before they’re microchipped, identical kittens are usually just both “Holly or Ivy” until they’re chipped and we have to decide which Holly and which is Ivy. We have chip readers at work, of course, and can use that as a reliable identifier.
They should, of course, be microchipped. It saved my cat’s life and got him quickly and safely back home when he got out and got caught in a possum trap and ended up in animal control. But I like the collar method if they tolerate it. It’s much easier to tell at a glance and people can understand and translate “Holly is the one in red” better than “Holly’s face is a little more square and Ivy has bigger ears.” It’s also adorable.
And they will develop and grow and start to differentiate themselves. Eventually you’ll roll your eyes at people who want to know how you tell them apart because, as far as you’re concerned, they look completely different.
My friend just told the story of bringing her twin boys (humans) home and not knowing which was which. The hospital had her bring them back in so they could look at the footprints.
Put a little wasabi powder on one of the kitties’ ass!
It may not assist in physically identifying them but you will have one kitty that loves you and a kitty that remembers you and hates you for life!
