I started making homemade milk kefir last year. It comes out light and delicious, no sourness. In this country people tend to say, just drink a cup a day. However my Russian roommate says people drink it all day, from childhood on. In the same vein, I searched this forum and found advice to give very little kefir to a cat, and I'm wondering, can more help and not hurt him? I mean, not a whole cup, maybe closer to 1/8 cup is all he'd want, and I'd build up very slowly since it can cause loose stool for a bit. But it's so healthy, effectively lactose-free, and full of the very best bacteria. What do folks here think?
