Yup, definitely. I give a dollop of tuna as an occasional treat, and sardines for their birthdays. :mrgreen: But land critters should be the base of the diet.
I think it's also important what you said about the wet/dry debate, and to make sure you always double check your information. There's lots of conspiracy theories about dry food out there and how it's poison, but really, it's not the complicated.
It's simply that cats have a weak thirst drive, so they don't drink enough water to compensate. They're dry-weather animals and they just don't feel thirst like we do. Long-term, that can cause issues. That's really the biggest reason wet food should ideally be the primary part of the diet.
Secondarily, people often don't realize that dry food has more calories by volume than wet because its starchy, and that's why both cats and dogs can get fat on it so easily, and the issues that can cause. They eat until they're full, and they don't know if that's 200 calories or 500 calories.
For some people, cost or limitations on ability or time can stop some people from going 100% moisture-dense diet, but there are people that are way too shaming about this or believe all sorts of crazy stuff about dry food. What's important is that we do the best we can with the information we have. For some people, the best they can do is half-wet. That's better than none! And for other people, they simply didn't know. And if their vet has never told them, why would they think there's anything wrong with it? Like I said in an earlier post, back in the 90's, everyone fed totally dry diets to their cats. It was less expensive, and there was no research about it. I can't blame my parents for doing that when no one knew.
It's striking the balance between being informed and doing your best, and getting mired in the misinformation that can be on both sides of this, or people who can get overly intense or uppity about how other people are doing. I've seen people get really crazy about this on pet care forums, and that just isn't going to help anyone learn more or feel compelled to gain more information. It just makes people defensive and angry.
I get a big bag of dry if I have to go out of town so the pet sitter can actually feed her enough, because she can only visit once a day, and I don't worry about that even a little -- I just make sure she has an extra large water bowl down. It's not poison, it's just not the best option for a main, long-term diet. And I've had people brow-beat me even about that.
I think of the pet food debate like politics, honestly. Question everything.
