It is interesting to note that, in wet cat food, Iams supplies fiber in a double fold. Purina One also takes the lead in almost all categories for dog food.

Protein Content

Protein is a very essential part of the canine and feline diet; this is because their body depends on it solely for wellness, vigour and life itself!

Protein contains the essential amino acids needed by cats and dogs. Protein increases dogs’ level of hyper activism and cats also use protein as energy.

Fat Content

Fat is, arguably, the most misunderstood nutrient. Here is the deal, your pet needs it in the right percentage. It provides energy in more proportions than carbohydrate and protein.

Apart from making food tastier, it helps pet’s skin to and hair retain its sleekness.

You don’t want an unattractive pet. Don’t worry, fat does not clog animal heart like they do to the human heart. Remember to only feed them with just the right amount.

Fiber Content

Ever wondered why every food label has fiber listed amongst nutrients? Without fiber, your pet will probably be constipated every other day.

It contains complex carbohydrates that aids digestion and allows nutrients to flow easily into the bloodstream.

💰 Price Comparison

Budgeting is critical to making a decision on what food brand to go with or avoid. You don’t want your pet getting to love that brand that you cannot consistently pay for. 

Budgeting can be very dicey; there is price per pound and price per calorie. The recommended metric will be to budget using kcal to avoid factoring in the moisture content that is inclusive while weighing per pound.

However, your shopping habits will help you decide what is economical or not.

  1. Not sure if this will be considered a comment or a ? but we feed our cats Iams and have for a few years. Our vet sells Purina One, he told us Iams is the best. We had 4 cats and now down to 1 original but we got another 1 who is not quite a year old. The 3 we had to put down were old, but they all had cancer of different types. Should we change brands as now the 2 we have are also starting to vomit and no hairballs so we don’t know what is causing this. Any advice if possible would be greatly appreciated. Sophie is 3 yrs and Slade is almost a year.

  2. Odd that a vet would sell Putin’s One ,but tell you Ian’s is best! He either gets more $$$ kickback from Iams, over Putin’s, or he don’t know what he’s talking about.
    Myself, I’d be looking for a new vet.
