hi imann and syunichi
hmm, does this lead to any known side effect for the cats? it sounds good that if it prevents more hairloss, then the cats will have lesser hairball problem.
right now i'm using a multi-vit Pet Naturals by Vermont. it's supposed to be good for cat's health including improved hair whether it reduces hair loss hard to say, i only vacuum my house about like once a week . Pet Naturals is sold in most pet supplies retailers and the price is RM32 for a bottle of 90 tablets. yes, it's in round tablet form and my cats would just eat them up but i do break it into smaller pieces for anna who has smaller mouth and teeth (using a pill-cutter/pill-splitter).
do keep me posted. thanks
