I've just seen a similar thread so appears ChampagneCat is not entirely fickle as others seem to agree with her.
She was on Country Hunter until that was discontinued, the. We moved to Katkin. She was fine with this and we bore the cost as she looked so well and the litter tray was the most fragrant a litter tray can possibly be.
Predictably now though she's gone off of it, a tray (handily labelled morning and evening) lasts 3 meals (a day and a half) and she's snarfing down biscuits while there's a bowl of the wretched slop in front of her 🙄 I also end up throwing some of it away on most occasions so we're on the search for a new food.
Cost is not much of an issue as we're currently paying for Katkin. She does need some biscuits as she has very bad teeth and we've been advised that this will help, she's currently happily eating Meowing Heads.
I tried to do a comparison but the array on offer is mind-boggling. I'm imagining something like Lily's Kitchen will be the way to go? We have a local Pets at Home and a large feed merchants. I'm also happy to order online and have freezer space one the bastarding Katkin has gone somewhere if needed.
