It seems easier to feed certain types of animals like; birds, fish and reptiles what they would naturally eat.
Cats and dogs are different, especially cats as they are true carnivores. Dogs can handle much more fruit and vegetables than cats.
Dogs can live somewhat healthy on a vegetarian diet. That diet would kill a cat.
When Diane and I got Cheyenne, we bought a certain brand of premium kitten food. One of those supposedly trust high end name brands.
Then I did some reading on the feeding of cats. Cats should really not have grains in their food. Well the food that I was feeling Cheyenne had corn listed as one of the top 5 ingredients! Corn? That's one of the worst things for cats!
When we got Angelo from the shelter, they said his interim guardian was feeding him Brand XXXXXXXXXX that was supposedly good for a certain system in his body. Well the first ingredient listed on Brand XXXXXXXXXX for this certain system in body was corn. Okay, maybe this food is good this certain part of his body... but what about the rest of him?!
Read the food ingredients on the pet food package carefully. One of the scariest things is, "Animal digest". Thankfully it's not found in too many foods.
Animal digest is made from 4D animals: dead, dying, diseased or disabled. That includes fresh road kill, animals that can barely make it to slaughter on their own and other people's pets that were put down by a vet, leaving the remains with the vet. Those foods containing other people's pets that were put down by a vet, also have traces of the chemical used to put down those pets!
Really good dog or cat food do not necessarily have to be expensive, but I'd rather pay the extra cost for the food than a vet bill that could have been avoided.
Feed yourselves well also!!
