I heard it was discontinued. Lately, haven't seen it anywhere. Checked a Tetra site, wasn't listed. I always liked to alternate between that and Tabimin for variety. Tried wafers years ago, but he didn't go for 'em. Bought diff. brand spirulina tabs 2 days ago (I thought they looked good), but just noticed--he hasn't touched them. Poor guy. Probably why he was looking at me like that this morning.
