The thing is, there is so little information, we really don't know if she owns them all.
She rescues them from the streets of Moscow, where they would probably die of disease if not freezing to death in winter.
She's currently got 131, but we really don't know how much fluctuation there is.
What if she is running a shelter?
My MIL runs one out of her home for mostly special needs or hard to adopt kitties.
How many are permanant?
How many are for adoption?
How many simply come by for a meal and then leave and go about their lives?
We simply don't know, as I said, there was really not enough information to make a judgement, other than the fact that they all look healthy and well fed.
