Peter Cohen, of Goleta, who currently has 15 rescue cats, has spent about $40,000 (£26,500) creating the kitty paradise.

He’s spent the money on building a colourful and intricate network of perches, tunnels, ramps and walkways.

“Way more expensive than a sane person would build, but I didn’t care,” he said. “I love my cats, my house and art, so I designed it to be beautiful to me.”

Mr Cohen says it brings him a lot of satisfaction knowing that he’s providing a safe and happy environment for his rescue animals.

“Giving rescued cats a better life means giving them a place that is solely their own,” he told Catster.

“They give us unconditional love, and building the catwalks is one way of expressing my gratitude for that.”

A video of his work has notched up close to half a million views on YouTube. It was first posted online last month but went viral this week.
