One is for dogs and one is for cats
Improved Answer:
There is more to it than the "cat" or "dog" label on the front of the packet or tin. Cats have specialised dietary requirements - cats are strict carnivores. Dogs, while predominantly meat-eaters, can happily scavenge if prey isn't available.
Cats have a higher protein requirement than dogs. Meat is mostly made out of Protein and Fat, and cats use these as their primary energy source.
Taurine: Cats cannot synthesize this compound (unlike dogs and most other mammals), so they must get it straight from meat. Animal tissues such as poultry and fish are natually high in taurine. Not enough taruine in the cat's diet can lead to heart problems and blindness.
Vitamin A is another component cats cannot produce. Dogs can use a compound called "beta carotene" (its what gives fruits and vegatables such as carrots the red-orange colour) and turn that into Vitamin A. Cats cannot. They need to get Vitamin A from meat.
There are also number of fatty acids cats cannot synthesize in their bodies but dogs can, so feeding a cat food specially made for them is the safest option as all the nutrients are included in the food.
cats and dogs look different cause cats have long whiskers and dogs have short whiskers.
Cats and dogs, it varies, there are different types of cats, and different types of dogs. I'd stay neutral on this even though I am a dog person.
They aren't. Dogs and cats are completely different species of animals.
No......They do not,do to my research cats are felines and dogs are different.
Dogs and cats are desended from the same creature, but they are in different orders.
No. They are both different species. Dogs = canine: Cats = feline.
Yes, dogs and cats can get lice, but they are different from human lice and are species-specific.
If non-dogs mean creatures that are not dogs then all cats are non-dogs, yes.Cats and dogs are two completely different species.There are many cats who think they are dogs (only when it suits them) and vice versa, that is why there is a saying: Dogs have Masters, Cats have slaves!!
dogs chase cats around because they are two different types of animals!
Because human beings like dogs and cats and keep breeding more different types.
there are different kinds but people usually keep dogs and cats.
No, dogs and cats cannot mate with each other because they are different species with different numbers of chromosomes.
