Casper Needs To Cut Back on Fat

We had our annual check up for both Casper and Cocoa this past Saturday.  Casper had his senior panel done and his fat intake needs to be reduced.  Also, needs to drink more water, tho honestly he drinks a ridiculous amount more than Cocoa does.

Anyway of COURSE they suggested a prescription diet which I wasn't having any part of.  I know we can change the wet foods he is eating with others which are lower in fat content.   I just don't know which ones off hand they are so, I could use suggestions.

Also, I am going to cut out the kibble completely.  We do use it at dinner time, 1/4 cup each but I realize that a) more wet would be lower fat in general most likely and b) it's too dehydrating.

So, what brands of wet can you suggest which aren't quite so high in fat?  Right now I give a rotation of the following:

Natural Balance Ultra

Chicken Soup for the Cat Lover's Soul - Adult

Various flavors of Fancy Feast Classics

Weruva - various chicken based ones

Freeze dried turkey - I forget which brand off hand, Orijen?

Instinct - various, beef, chicken, venison

I know there's probably a couple of others I just can't remember right now.

Treats are not a daily in our home.  He gets freeze dried chicken or turkey 95% of the time for treats.  Rarely bonito flakes (I can't even remember the last time).  We do give home cooked chicken or fish sometimes - but are careful to make sure there are no seasonings or added anything.

While I'd love to do raw, we can't at this point in time.  Have considered it but it just will not fit into our lifestyle right now at all.

Of course, this would benefit Cocoa too since she gained a lot of weight since we got her in 2012.  Poor thing was underweight but she's remedied that and then some LOL.

Thanks!

The Tiki Cat chicken varieties are very low in fat, so that one would be good to add to the rotation.

Question, out of general curiousity why does your vet want the fat reduced specifically, as opposed to overall calories?

The blood work showed his fat lipids as being elevated.  Or something like that - I'm at work and it was hard to have the conversation on the cell phone.  So, I think they are saying whatever he's eating is too fattening.  The women kept asking me what treats I give (and again, all relatively low fat) for example.  

But also they want me to reduce what he consumes.  We had gotten him down to 14 pounds more or less and he gained some of it back this past year.  So, evidently there's too many calories going in also.  

The kibble we give is pretty high calorie - I do know that.  We only give 1/4 cup each and many mornings, there's some left over.  Of course, I have no idea which of them is eating how much of that - and since she's gained too I would think both are just eating more or less of their own.

The kibble they get right now is Instinct which has freeze dried pieces in it also.  Again, I'm at work (trying hard to leave!) but I can post exactly what it is later.

Also, beef is in their rotation of foods also in the wet foods mentioned above.  And, some rabbit.

Oh, and some small crystals showed up in the urinalys. He has had a UTI in the past, once, a couple if years ago. Definitely want to avoid that again.
