What breed is my long haired pointed cat?

I think she could either be a Balinese or a pointed Siberian Forest cat, but i'm not sure, so i'm here for a more expert opinion

Was she shaved?

Yes

A beauty!  I think you can compare her with Neva Masquerade, ie a  sort of  pointed Sibirian.

Sibirian proper, nor MCO nor Norvegian Forest,  none of them are normally pointed.   None or very few siameses among their ancestors.   

Lynx point, or tabby point, is what the pattern is called.

Good luck!

Neva  can be interpreted as New, if you like.   But really its the river floating through St Petersburg.

And Masquerade is hinting to the masque, ie Point color.

So the name is a nicely found play with Words.
