I read this book around 2013/14 and I just cannot for the life of me remember. The novel centers around this juvenile cat which befriends a dog and takes revenge on some rats which killed its siblings when it was a kitten very shorty after their birth. The dog is also adopted as a puppy some time after the kitten. Their humans are involved in the storyline too but not majorly. Any help would be appreciated:)
