Tim Hortons Field really is the home of the cats.

The stadium that hosts the Hamilton Tiger-Cats also became the birthplace of three kittens, in a wall near an elevator shaft on the fourth level.

The felines were gathered up Wednesday morning by construction workers. They've since been adopted out after senior project co-ordinator Trish Marianovits spent a day caring for them on her desk, causing some colleagues to dub her "the den mother."

The kittens are solid black, solid grey, and black and white respectively, and "absolutely adorable," according to Marianovits.

Worker Cory Rogers took one home and says he will leave it to his family to name the new pet.

Are the births an omen for the Tiger-Cats and their future games in the stadium?

"They're 3-0 now in the stadium," said Gareth Barkey, site supervisor for Ontario Sports Solution, which is building the $145-million stadium for the 2015 Pan Am Games. "Something good must be happening."

Barkey said the mother has been observed around the construction site since crews arrived, coming and going as she pleases. At one point, he said he noticed her belly had expanded and thought she might be carrying kittens.

"How she picked Level 4 for a home, but she did and now she is out of sight," he said. "They were content, rolled up in a little bundle up there, but it's not exactly a permanent home we can give for these guys."

Barkey and Marianovits said the discovery of the kittens has dominated the chatter among workers and visitors on the site.

"Big-time," laughed Marianovits. "Everyone has been stopping by and looking at them. They are such big sucks."
