For a while, everybody was on Taste of the Wild, three cats and the first dog, but it didn't agree with anybody. Very smelly and loose stool, so once they finished she switched the dog to Fromm, which is cheaper than TOTW, and started buying cheaper food for the cats. Then I started buying the cat food and we got another dog, then Freya got extremely sick and I'm struggling to afford the cat food.
I think the main reason she's willing to pay for the dog food is that she paid for the dogs, but I really have no clue. She has these weird mood swings when it has anything to do with the cats, but I'll definitely tell her about the tuarine :/ I can't remember what lysine does, but my vet suggested me giving it to Freya for her medical issues as an extra boost.
It doesn't really have to be single protein, Telmo should be fine on duck, turkey, beef, and venison. He was on California Natural, limited ingredients which he liked but was a little pricey over here.
Thanks for teh quick replies guys, you've all been really helpful
