How much wet?

I'm switching Mollie over to an all wet diet - so far the addition of wet has been amazing. She has had GI issues, and since she started eating wet she's had no issues (no loose stools or vomiting - yay!). I do have a few questions though
1- How much wet should a 10lb. female cat eat? I've been buying the 3oz. cans (Pro-Plan and Pro-Plan Select), dividing them into thirds and feeding her 1/3 morning and 1/3 evening - followed by 1/4 cup dry Nutro Natural Choice at night. We are almost out of the dry, and once she goes all wet, how much should I increase it to? If I read the back of the can right, she would be eating about three 3oz cans a day and I just can't imagine that (she never begs for food and never seems hungry - although she does get excited when the wet comes out ).
2- What is a solid wet to add into her diet for a rotation.
3- Why are so many people opposed to by-products? Don't cats in the wild consume most of their prey (i.e., eat the stuff that we think is yucky)?
As always, thank you SO much for all of your help and knowledge!!!!!

I will Explain IMHO

For a cat an all wet diet generally would equal .5 to 1 oz per lb or for a 10 lb kitty 5-10 oz of wet per day or 1and 2/3 cans to 3and 1/3 3oz cans
2- What is a solid wet to add into her diet for a rotation.
I Look for one WITHOUT colors ( red , artificial ), artificial flavors , grains prior to the 5th ingredient( many at all levels are grain free

)

A Healthy well fed cat will not eat the entire carcass.... IMHO some by products are fine in a wet food... The Issue is the Lack of knowing Exactly What and What amounts they have in them ..See in a dry food By products could be 75% bone, 20% sinew/ connective tissue and 5% organs... We DO NOT know is the issue... that is not how they come in nature.... Plus many by products are processed differently ... Also think about that Fresh bird vs the chicken in your grocery store ... a little different

Tolly, 11+ years old, weighs 9.5 pounds and eats 6 oz of canned a day with 1 tablespoon of kibble in snacking

Jennie, 4 1/2 years old, weighs 10 pounds and eats 4.5 oz canned a day with 1 tablespoon of kibble in snacking

Each of these cats eats a different kind of food, and each has different energy levels.

My point being, it all depends on the cat and the food you are feeding.

Feed her 6 oz a day and if she gains, cut her back, and if she loses feed more.

PS Hurray for you for putting your cat on a canned diet!

Mist is 14.5 years old, weighs 8.6 pounds, and is fed two 3-ounce cans / day divided into four servings.

As a diabetic she gets Proplan Kitten chicken and liver in rotation with Fancy Feast Beef Classic (brown label) and FF Turkey & Giblets classic (olive label). Both FF have no corn gluten and less than 10% carbs.

She'd happily eat more but her weight remains stable with this amount of food.

Now, if I could only manage to reduce my own weight . . . .

Thank you all!
