It's expensive, but it's good food. Why would you want to go back to kibble? Convenience? Price? Rotation?
If it's rotation, you can rotate base mixes (between THK's two kinds, or even other companies like Sojo's, Dr. Harvey's Veg-to-Bowl, etc.) and proteins.
If it's cost, Sojo's base-mix with grain is a lot cheaper (and comes in giant-size bags), but you will be getting a lot of grain as filler, so it's a step down in quality in my opinion. Or stay with THK and order it through onlynaturalpet.com when they have good coupon codes, and stock up. I buy about 2-3 mo. worth at a time when they send me a good code, which often gets it down to about $45/box instead of $57.
If it's convenience, you can make busy work/school mornings easier by preparing about 2-3 days worth of base mix at a time in a giant mixing bowl with a lid, and storing it in the fridge. Then you scoop it out at feeding time without having to wait for it to reconstitute. I keep a separate bowl of meat, so I can pull out my two bowls and scoop at meal time. It's much faster than adding water and waiting for it to reconstitute!
