Gender of kitten?

Just wanting to double check if girl or boy, I was told a boy and kitty has vets next week :-)

What a beautiful kitten.   If you look from behind and ask someone else to lift the tail, you will see your kitten's anus.  This is normally an obvious round hole with a muscuar border holding it closed.   This is also where the poo comes out. Below this, you can expect to find one of two things.  A female will have a short, separate 'slit' very close to - and below - the anus.  A male will have a second round hole, but depending on the size of the kitten, there could be a gap of between one point five and three centimetres between the two holes.  The bottom hole is the end of the penis, which points backwards in a cat and the shaft of which is usually sunk into the surrounding tissues.   There may or may not be descended testes between them, depending on the age of your kitten.   I cannot see enough on this photo and am very wary of giving answers without enough context.  I will have another look on a different screen later in case there is more to this picture than I can see.
