Kaley Cuoco's 30th birthday was her best ever.

The actress went with her sister and friends to the Black Jaguar White Tiger Foundation in Mexico to celebrate her birthday, and had the trip of a lifetime. The Black Jaguar White Tiger Foundation rescues big cats from "bad circumstances," according to its site.

"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 of..you are the reason this planet will change.."

Cuoco cuddled with tiger cubs at the sanctuary with a dozen of her best friends as they celebrated both her birthday, which was on Monday, Nov. 30, and her sister's birthday, which was on Sunday.

The "Big Bang Theory" actress posted tons of photos of adorable tigers and other big cats; she and her sister also celebrated their Mexican birthday trip with sombreros and a pinata. Former "Bachelor" and "Bachelorette" star Ali Fedotowsky joined in the festivities, and posted a photo of herself with Cuoco while they played with a baby tiger. Fedotowsky called the celebrations "the most epic, memorable, fun, once in a lifetime trip!!"

It hasn't been the easiest year for Cuoco, who announced her divorce from Ryan Sweeting in September, after 21 months of marriage. She recently covered her tattoo that marked her wedding date on her back.
