Is it that she possibly needs certain carbs like rice to help her? It's possible the type of wet you were feeding wasn't compatible with your cat, rather than "wet food caused constipation." Your kitty may have motility issues, or a problem in tone, etc. I hope your vet can get her straightened out.
So, an update on Enya. I took her to the vet today and she was indeed constipated. As odd as it is and as contrary to cat knowledge as it is, I think being on entirely wet food has constipated her. While yes cats are obligate carnivores, I feel like we also have to keep in mind that cats have been domesticated for a few hundred years and some cats have probably evolved to depend on the fiber present in dry foods. For now, I am going to return to doing half wet and half dry as that seems to be what works best for her. Wet is in no way being taken out of her diet ever, but it seems I am going to have to go against all logic and do half wet, half dry again.
As of right now, she is at the vet’s and they are administering an enema and cleaning her out. Ugh, cats can be as complicated as humans. Hopefully this will work. I am going to have to take her in at a later date to have her tumor x-rayed so we can determine what to do with it.
FWIW, dry kibble has only been around for cats since either the 1940s or 1950s from what I've read.
