Any Vegetarians/Vegans here?

[Aractus]

He actually thinks animal proteins are made of different substance than vegetable proteins he REALLY is that uneducated.

You clearly have no idea what proteins are do you? Some people think that cats can't see colour - of course they can, but just like any other animal (humans included) they can't see colour at night. However they can see in less light than we can because they have a rod-to-cone ratio of 25:1 (ours is about 4:1). In addition to this they have a layer at the back of the eye called the tapetum lucidum (built using zinc protein) that behave as a mirror and effectively double their low light perception - so they may as well have 50 rods for every cone. Cats do not produce the zinc protein, and as far as science can tell it's not found anywhere in their DNA to be potentially constructed. But they're completely reliant upon it and a lack of zinc in their diets can lead to serious health problems including cancer - not just the loss of night vision.

You can see here that PETA says to feed your cat or dog a Vegan diet.

Now let's look at what professionals say.

• Why Your Cat Needs Animal-Based Protein
  
  The protein in animal tissue has what is known as a complete amino acid profile. Amino acids are the building blocks of protein. Proteins derived from plants don't contain all the amino acids critical for the health of an obligate carnivore.
  
  You have the physiological ability to turn plant proteins into the missing pieces needed for a complete amino acid profile. Your cat's body isn't equipped to do this.
  
  One of the amino acids missing in plants is taurine. Taurine is found in animal muscle meat, especially the heart and liver. Taurine deficiency causes serious health problems in kitties, including blindness and heart disease. Feeding a cat a taurine-deficient vegetarian diet, then supplementing with a taurine pill is similar, in my book, to eating iceberg lettuce as your sole food source and taking a synthetic multivitamin. It doesn't balance out.
  
  

There you go.

• If you REALLY want to feed your cat a vegan diet:
  
  Some people want to make their pets vegan because of religious reasons or personal beliefs. My advice to you would be to consider not having a pet. It is unnatural to take a carnivore and ask them to eat a vegan diet.
  
  I’ve focused on cats here. It is possible to have a dog be a vegetarian. (There is actually a prescription vegetarian food.) This is because dogs need 2-3 times less protein than cats do. I still don’t recommend making your dog a vegetarian or vegan, but if someone is adamant then I’ll recommend a prescription vegetarian dog food. But there is no safe way to feed a cat a vegan diet.
  
  

People can have a perfectly balanced vegetarian diet - but this is not true of vegan diets. Vegan diets are dangerous, they lack essential nutrients that we need - not just proteins, but other things as well. Dairy is one of the easiest ways so supplement a vegetarian diet to get these required nutrients - what you are advocating, and I have already proven, is a diet that if followed without buying any processed foods is deficient in a number of areas, particularly B12 - and a B12 deficiency can permanently harm babies just like smoking and drinking while pregnant.

Also, it is unsafe to give a Baby vegan formula. It can result in DEATH!! If breast milk is unavailable - Babies have to be given formula made from cow's milk. You must acknowledge this point.
