If cats can be on vegetarian diet?
Certainly, cats can be vegan. You can find a lot of disinformation, different theories and views concerning why many people insist that it cannot be done, but again and again, people have shown it is not only feasible, but a better diet than what they had formerly been feeding.
No matter the views of the "pros" who are frequently either misinformed or are basing their thoughts on premises, we've seen firsthand that for many creatures, it's an extremely healthful diet they can stay on for their whole lives.
Obviously, animals are like people - every one is distinct, and as some individuals cat can transform from one diet to another without any problem, while others may not discover it to be so easy.
We have not heard of a cat who didn't do well on vegetarian diet, so if you are interested in a complete transition, it is good to begin primarily with a 50:50 balance of vegan and non-vegan food.
Many cats have trouble assimilating soy, that along with soy`s naturally big phytoestrogen content, makes this protein source fundamentally debatable for felines. Corn gluten meal comprises about 60% protein, but also a substantial percentage of carbs. Corn has a high glycemic index and is a vital variable in the growth of feline diabetes. (Unless it says that these things are all-natural, they may be specific to be GMO.)
Speaking purely from a veterinary point of view, vegan diets for cats make me anxious. I've seen some really ill cats as an effect of such diets. The results of these diets can sensibly be anticipated to contain obesity, diabetes, urinary tract disorder, kidney disease, allergies, asthma, inflammatory bowel disease, liver disease, and more.
As for me, I consider that when we willingly embrace cats into our houses, we're ethically obligated to respect the feline spirit and feed them according to its fundamental nature. But it is only one point of view.
