Kaley Cuoco‘s animal family keeps growing.

On Friday, the Big Bang Theory star welcomed puppy Chester Cuoco with an Instagram post and a string of hashtags, after adopting him from Paw Works, a California animal shelter.

Cuoco, 29, said earlier this week that she was “completely overwhelmed with the outpouring of kindness and support” following news of her divorce from tennis star Ryan Sweeting, which was revealed exclusively to PEOPLE in September.

“I want you to know, I read all your comments and your sweet words have touched me deeply. I’m incredibly grateful for all your love as I start this next chapter in my life,” she posted on Instagram Wednesday.

The day after announcing their split, Cuoco introduced her newest horse, Zaza. She has attended multiple horse-riding events in recent weeks – including one in full Jedi regalia.

Cuoco is “extremely focused and high-energy,” a source previously told PEOPLE.

In an Instagram post the day before she adopted Chester, Cuoco posted a photo of the pet family he would be joining, all snuggled together.
