The Flight Attendant star, 35, announced on Thursday that she has retired her equine companion — nicknamed "Netty" — from competing in horse shows. "For the last 6 years, my princess Netty has been nothing short of amazing ... She was the first 'real' horse I ever sat on, and was the first in my official string. It was love at first sight," Cuoco wrote alongside an Instagram slideshow of herself and Netty throughout the years. "My first jump on her in Calgary, was a moment of 'whoa'. I knew I would love her forever and that she was perfect for me," she recalled. "We won our first class together and our last. Our magical moments together are too many to count! From taking me to Spruce to Meadows to indoors at the LA Longines Masters never getting a rail and a blink of a second from 1st." Kaley Cuoco and her horse Bionetty.

"She hated flatting at home and would literally rip our arms off at the trot. So I decided she's a horse show horse. And that's what she was. A performer. Like me. Maybe this is why we are soul mates," Cuoco wrote in her original Instagram post. "We share the same heart." "I hope Netty knows retirement doesn't mean her life is over," she continued. "I feel this is my way of thanking her, with a brand new life. Living forever in our backyard, having babies and getting constant pocket mints from my dad." Cuoco concluded, "Bionetty, there will never be another like you. You will always be my Queen B! 🦄 (ps. The gold boots are forever yours ⚡️)" Kaley Cuoco's horse Bionetty.
