Kirsten Dunst's cat is missing.

The 'Melancholia' star's beloved feline Tazzy reportedly escaped from her Californian home a few weeks ago and the actress has been searching desperately for her pet, though she fears she may never return as the animal wasn't wearing a collar.

A source told National Enquirer magazine: ''Kirsten is heartbroken. She and boyfriend Garrett Hedlund put up posters all around her neighbourhood offering a reward and hoped someone would turn Tazzy in but no luck so far.

''Tazzy wasn't wearing a collar so it's possible she'd be mistaken for a stray.''

Kirsten isn't the only star to have recently lost a pet.

Kendall and Kylie Jenner have been searching desperately for their Chihuahua Dolce after he escaped from a friend's house.

Kendall said recently: ''We still can't find him. We've had him for like 10 years.

''He was staying with our friends for a little while. They've been friends for a long time and they really loved him... and then he got out.''
