I adopted a cat who lived one year in a shelter, she won't eat any wet food, I feed my other 3 cats once a day Sheba wet food, how can I get here to eat some wet food, she just sniffed it and walks away, any help is appreciated.
It's more important for your cat to eat quality food, than whether it's wet or dry. You may or may not be able to get your cat to eventually eat wet food. If your cat will eat dry food, feed her a high quality dry food from a manufacturer with a tested track record, but DO NOT free-feed, giving her only amounts based on her target weight (that your veterinarian can tell you). Have a water fountain for her, and bowls of water, and encourage her to drink from the sink or bathroom tap, which many cats love to do. Cats have lived long and healthy lives on dry food for decades. I agree that wet food is preferable because of the moisture content and lower carbohydrates, but it is by no means a requirement for a long-lived healthy and happy cat, if you manage her dry diet with care and smarts.
@catlady1950 She may just not like the flavor. You could try a wet food made with a different type of protein to see if she has any interest. If not, it's not a big deal. Like MREG376 said, wet food is preferable for several reasons but it's not an absolute must. You can supplement your cat's moisture intake by soaking her dry food in water or broth and offering plenty of fresh water (running water seems to be particularly enticing for cats, so maybe try a cat fountain). Just be sure that at least 90% of your cat's daily diet consists of a nutritionally complete cat food.
