Constantin is a supporting character in the television series 101 Dalmatian Street. He is the Dalmatians' next door neighbor.
Constantin craves peace, quiet and dignity, but he is ritually robbed of all three on a daily basis due to his dotty dog neighbours. Constantin enjoys hosting zen parties and yoga sessions for his fellow feline friends and Deepak, his spotty protégé. He lives a minimalist lifestyle in a sharp contrast to his messy neighbours.
Constantin is a cat with blue-grey colored fur. He has thick white eyebrows and white fur going from his muzzle down to his chest and along his stomach.
