GiantKitten, it must be the tins, unless the recipe is different. The good stuff from Zooplus/Germany was sometimes acceptable, but a can of Whiskas or Butchers would be sniffed and ignored.
It’s exactly the same stuff as far as I can tell, so it must be something about the tins!
They hoover up the pouches but walk away from the tins. I also tried buying various Really Good Brands from zooplus but they never appreciated those either.
The Felix tins are somewhat cheaper, but the pouches only cost about 40p per day per cat, & they love them, so I’m not going to argue
(And there’s no grain in them - the only evil is some sugar. )
They also get Royal Canin neutered female biscuits (even the boy) which appeases my conscience.
Re the little sponges, have you ever tried cellulose? The nylon ones are basically useless & just spread water around but cellulose are great & leave surfaces almost dry.
Supermarkets used to have them (I like the ones with scourers on the back) but they all stopped; Amazon seems to be best source now though I’ve just discovered Waitrose still do them.

Or, have a look at the glorious Swedish ones I linked earlier
