I'm finding the replies to this question really interesting as I have been wondering the same over the last three weeks since having my two new boys.
Prior to them arriving with me, Anoosh would eat ANYTHING that was put in front of her (and sometimes stuff that wasn't
) due to her 'history'. Originally, she had come to us with serious tummy problems due to scavenging for food and we were advised to put her on to Oscar's dry food by our vet. It worked for her, and she loved it. However, after a while, I thought about introducing some wet food for her and as our other cat at the time liked Felix, that what Annosh had. But they both only liked the fish varieties and hated the stuff in gravy.
But these boys! Picky eaters or what!?!
They're not keen on Felix. (shame, as I stocked up when there was an offer on!) They didn't mind the couple of Whiskas pouches that I tried them on (Oh So Fishy, or something - very palid looking stringy fish in jelly.) They were okay with the Sheba trays but didn't seem overly taken with them.
Then I found the High Life 'petit pate' stuff which is in TINY little tins - 85g and very expensive by comparison. But the tuna & chicken variety contains min 55% tuna and 5% chicken and they seem to really like it. Should I be concerned that it contains colourant and preservative? It seems like most stuff I've looked at tends to . . . . Anyway, what I *have* noticed is that the can says that an average adult cat should eat 2-3 cans of this stuff per day but my three have one can served between the three of them, mixed in with a sprinkle of biscuits as a meal - and then still leave some. They just don't seem to eat much at all - and Alfie & Wilf weigh 6kg each so I thought they would eat for England. . . .
I was in a town yesterday where there is a Wilkinsons, which is a bit of a novelty for me as there isn't one where I live. In their cat food aisle they had a four-pack of 'HiLife Cherish Gold' , each tin being 156g (tin-of-tuna size). It was 98p for 4 and the meat content was over 40% so I bought a couple of packs. I don't know what I was expecting but I opened a can for them last night and it was literally whole big chunks of sardines in a thick jelly.
Wilf and Anoosh went mad for it whilst Alfie looked at me with disdain so I ended up opening a tin of something else for him . . . . . . .
We don't have a Pets At Home anywhere near me and so some of the food you are talking about is unknown to me - maybe I need to go to an independent pet shop or something - but then the cost does start to mount up! I'm not saying the three Floofs are not worth it, but it's always nice to be getting a bargain, eh?!
