Pet

Madhavan, who is a vegetarian, endorses the brand, PETA. Since joining them after starring in his first film, he has appeared voluntarily in several advertisements and released an E-Card for the brand. In July 2006, Madhavan was voted the "cutest male vegetarian" by an online poll conducted by the NGO, People for Ethical Treatment of Animals (PETA), while Kareena Kapoor won the female award respectively.

Despite winning the public-voted poll, Madhavan was then questioned at his home for keeping an African parrot as a pet. The pet was not confiscated, with Madhavan labelling as himself as an animal lover with two dogs and a parrot, which he claimed was like his "second son".
