Kaley Cuoco celebrated her 30th birthday over the weekend the right way — with her sister and her friends in Mexico. But it wasn’t the kind of trip you might be imagining — the group spent most of their time at the Black Jaguar White Tiger Foundation, whose mission is to “rescue big felines from cruel circumstances and provide them with the best lifestyle possible,” according to their website.

The Big Bang Theory star and 12 of her closest friends celebrated her birthday (November 30) and her sister’s birthday (November 29) by cuddling with adorable tiger cubs and other big cats at the animal sanctuary. Lucky for us, Cuoco documented her extraordinary trip on her Instagram page.

She wrote, “Today was the best birthday I have ever had … Thank you for all the love and best wishes .. My heart is overwhelmed with joy and complete contentment. there have been a few bumps along the way, but thank you God, nothing I can’t handle.. Thank you to my precious little angels who accompanied me on this trip and gifted me with something so special (they know what I’m referring to) thank you to Eddie @blackjaguarwhitetiger@paulcheca for showing us your beautiful sanctuary- how you have saved these animals from abusive , confined lives and now they are living a life they never could have dreamed are the reason this planet will change..”

To date, the Black Jaguar White Tiger Foundation has rescued over 200 big felines including jaguars, tigers, lions, leopards, lynxes and pumas. All of the animals have been given a safe home at the sanctuary and are surrounded by “love and a whole lot of trust”.

We love all of her pictures so much, and absolutely love the idea of doing something so meaningful for a 30th birthday (or any birthday for that matter).

Of course, it isn’t a real Mexico trip without traditional sombreros and a pinata.

The entire birthday squad.

Happy birthday to the Cuoco sisters!
