So much more than Grumpy Cat: Philadelphia photographer sets out to prove that cats have feelings too with a series of stunning pet portraits.
Cats may want you to think they are aloof and unemotional, but every feline fan knows that's just not true.
Now a Philadelphia-based photographer has set out to prove that cats have feelings too, by documenting a whole range of cat emotions.
The series of amazing portraits captured by photographer Andrew Marttila show just why so many people are fanatical about cats.
The 29-year-old photographer, a self-proclaimed 'crazy cat man', has even partnered each of the portraits with the emotion he believes his subject was feeling at the time.
He said: 'This series on emotions is to disprove the stereotype that cats are cold and aloof.
'I want to show that cats are capable of a range of emotion, from serious to silly and everything in between.'
