Hello All!!
I wanted to let everyone know that Bieli is doing great. She went to the vet and the vet examined her and said it was simply excessive hair = hairball. It is summer here and so the shedding is almost double. (Considering she also grooms her brother, that's almost 4x the excess hair she is intaking??)
He did put BOTH of them on Laxatone and I'm sneaking that into their wet food and no hairballs in over a month!

So thanks to everyone! Have a happy one!
