Last time I raise it, I promise.
But do have a look at the (sometimes conflicting) cat nutritional requirements.
The majority of brand name cat food has very high levels of carbs.
I know you (in a very minor way I admit)
You don't want to feed your cats ingredients just because "that's what we've always done"
Just check out what additives there are. What carbs there are. What SUGARS there are. And read some anti-processed food websites.
I know you'd do it for your kids
(and you and your cats are currently skinny in a beautiful way
)
Oh, and ... it being too late for LJ... I mean... a photo stripped to the waist and I would eat my words... and it would sound like mmmmmm.
