Hi there,

If they're both already on a dry food, I'd suggest you keep them on whatever it is until you come back. If they're not on a dry food now, I'd suggest Orijen or Applaws dry.

Then, the wet food for Logi; it sounds like he's either just got a sensitive tummy, or he's sensitive to the particular meat that was in what you fed him. Have you tried different versions of the brands, or were they all chicken for example? Also, when you switch to the new food make sure you do it slowly, by mixing it with his current food in small amounts. Increase gradually and he may find it easier to adjust to.

For Lance; is he getting any supplements for his arthritis? I suspect the vet has told you to keep his weight down and for this the best you can do is feed him a high meat content wet food. Never mind any 'light' foods as they contain more carbohydrates which again will make him put on weight. I'd suggest you get Lance on the same food as Logi, assuming you end up on a high quality wet food such as Porta21 or HiLife pouches. I don't believe in kitten/adult/active/couch potato/senior/outdoor/indoor/any breed/light formulas, I think they're all just clever marketing and that any cat at any age will be fine eating a high meat diet. Of course, you'd need to adjust for any illnesses the cat may have, for example arthritis where I've heard of adding a glucosamine supplement. You'll want to check this with your vet.

Hope that helps!
