Meet Nova the Pomeranian Husky and Helmet the cat.

Ever since he was a puppy, Nova has been trying to get Helmet to play with him.

But Helmet just won't play ball.

The pomsky has been pestering her brother Helmet the cat for a year at home in Lincoln, California, trying to get him to play with her. Here in a compilation of three clips - showing a tiny Nova and an older one - her attempts are met forcefully with Helmet's claws.

Helmet was "very unimpressed" with the new family addition, says the owner.

"I give it to our puppy for determination though," she adds.

My pomsky Nova doesn’t understand why our cat won’t come down to play with her. our cat Helmet is very unimpressed with our new family addition. I give it to our puppy for determination though. Love that she tries every side of the cushion looking for a way to reach Helmet
