The cat, named Tara, was captured on a security camera May 13 when she pounced on a dog that attacked her 4-year-old human, Jeremy Triantafilo.
The video, which has garnered 21 million views on YouTube, shows the dog biting and attempting to drag the boy. Within seconds, Tara leaps out and chases the canine away.
Jeremy needed 10 stitches in his left leg after the incident.
Ryan Triantafilo, Jeremy's father, said he edited the video and posted it on YouTube for family and friends to see and that he never anticipated the flood of attention.
Tara, who followed Ryan and his wife, Erica, home from the park one night, has been smothered with love since her heroics.
"We've just given her a lot of love, kept her in the house and paid a lot of attention to her," he said.
There was a failed attempt at the game, between the Blaze and the Lancaster JetHawks, to have Tara "throw" the pitch using a baseball attached to a fishing line.
Instead, Ryan Triantafilo helped the cat "throw" the pitch as he held her in his arms. Meanwhile, Jeremy threw the game's actual ceremonial first pitch.
