You don't know the whole truth dude, actually you drink from its cup )
I that case, an appology towards the cat is in order.
I let my cats stick their noses in my water bottles. It's very cute.
In what form is чашки here? I am having difficulty understanding the conjugation in this case.
Singular, in genitive case:
I put "Your cat is drinking from my cup" Should this be accepted?
Yes, your choice is correct. Click on the "report button" if this one wasn't accepted.
Drinks what, exactly?
