Some people never write a book. Now Grumpy Cat has written two.

The feline became an internet sensation after her scowling visage became synonymous with melancholic disenchantment.

Her first book, Grumpy Cat: A Grumpy Book, was a guide to attaining "true grumpiness" from the self-appointed "master of bad attitude".

Helpful tips included eating ice cream cones to get incurable brain freezes and reminding yourself that a kiss carries more germs than 100 toilet seats.

The follow-up, The Grumpy Guide to Life, promises to carry on where her first book left off.

Now a famous author, Grumpy Cat has rubbed shoulders with celebrities such as Ian Somerhalder, Johnny Knoxville and Seth Meyers since making the A-list.

The new book will be out in August.
