Can any of our creative jellies help me to come up with a cute message to go on this unconventional marriage announcement?

My aunt and her boyfriend are getting married, both for the first time and they are in their late 50s/early 60s. They don’t intend to really tell anyone their plans until after they have already gotten married, as our family is spread out all over the globe.
Instead, they want me to make a little graphic with their two cats dressed up as a bride and groom… so that they can mail/email family members and announce that they’ve gotten hitched.

My aunt gave me a rough copy of what she would like the graphic to say, but she said she’d like it to be more creative/cute/poetic. I told her that I would post here on Fluther, since we have so many creative jellies. Yes, I was bragging about the awesome people here.

This is an idea of what she’d like it to say:

”BoyKitty and GirlKitty would like to announce the marriage of their “people”
FutureUncle and Aunt on (date) at the county courthouse in (city/state).
They’ve been together for awhile, so it’s about time they made us legal!
Here is their story. Boy, they sure did everything inside out!
They adopted us first and then they went on a honeymoon to _Wyoming and Montana (they didn’t take us with them) and then came home and got married.
…and they lived happily ever after!”

Any creative ideas are welcome.
