"I'm a big animal freak. I'd rather the animals be there than real people," Cuoco laughingly told Craig Ferguson during an appearance Wednesday on The Late Late Show. "The whole farm's going to be at our wedding."
The avid horsewoman also revealed a secret desire for her wedding – to arrive on horseback.
"I might ride in on one of my horses," she said. "I secretly want to do that."
Sweeting, 26, popped the question to Cuoco, 27, in September after just three months of dating, and although she recently admitted to PEOPLE that she hopes to marry her man "as fast as possible," she doesn't want to skimp on the details.
"I've been planning my wedding for about 27 years, so I've got it planned out in my head," she explained to Ferguson.
However, she wanted to make one thing clear: She is not a Bridezilla: "I just want everything the way I want it," she joked.
Everything she wants could potentially include some offbeat ideas, including a wedding cake in the shape of her three pit bulls.
"I'm obsessed with my dogs, and wanted to do a cake in the shape of their heads," she said.
When Ferguson wondered whether the cake would be big enough for all her guests, Cuoco proposed a solution.
"I thought I would put the horses on there, too," she said with a laugh.
