Nutricia Fortisip Compact Protein Vanilla - 4 X 125ml (Pack-16 X 125 ml)

Handy smaller bottles - useful because they can go off when used for a lactose-intolerant animal before the bottle is used up. For animals, we dilute an amount by as much water again, and if necessary freeze the resulting liquid in one of those bags of 'ice' cubes where it's essentially lots of tiny plastic bags joined into a sheet, and you pour the liquid in at the top and it seeps through to all the wee 'bags'. To remove one, you just snip the 'ice' cube off, and peel off the plastic. Frozen in any other way, Fortisip ends up as a gooey mass for most of the 'ice' cube, with a tiny bit of liquid at the bottom. Damn good product though and wouldn't buy anything else for the purpose

Upset my stomach so badly. And many others have said the same thing.
