A ginger cat never left the side of his little human brother from the day they found out that their baby had a broken heart.

Siggy the cat met his little baby brother Isaac when he was born 13 days overdue. "We came home that same night when he met Siggy for the first time," Kirsty Jai Skelton told Love Meow. "Siggy sniffed him, rubbed his head and fell asleep next to us."

"Isaac turned out to be seriously ill with multiple heart problems (he's just had his first open heart surgery at 12 weeks old) and I think Siggy knew because he would sleep under Isaac's moses basket whenever Isaac was in it, like he was guarding him."

When they first met, Siggy snuggled next to Isaac and started purring.

Siggy was very protective of his best friend. He never stopped purring when he snuggled with Isaac as if he was trying to help him heal.

"Isaac went into hospital for over a month when he was 3 weeks old and Siggy went to stay with a friend, and when we came home and fetched him he was doting on Isaac," Skelton told Love Meow.

Siggy's love really helped little Isaac fight his battle. Today Isaac is out of the hospital and is doing amazingly. "He makes me so proud, he's always been the happiest, most affectionate baby. He's not let it keep him down!" Skelton said.

Siggy seemed to know that Isaac needed some extra love, so he kept him company and had his purr motor on at all time.
