Cheese nips are small cheese flavoured crackers which are popular in many places around the world as a snack.
They are made in Cheddar, Reduced-Fat Cheddar and Four Cheese (Cheddar, Parmesan, Romano, Mozzarella) flavors. They were once made in extra cheddar flavors. The Four Cheese flavor contains half a gram of trans fat per serving. (Wikipedia)
So can guinea pigs eat cheese nips and if they can how much of them can be eaten.

Let’s take a look at their nutritional data and looking especially close at their fat, sodium, calcium, acidic, phosphorus content which is especially pertinent as far as guinea pigs are concerned.

As you can see cheese nips are quite high in sodium and fat which means that guinea pigs shouldn’t have too much of them. If they do happen to eat a few of them, they will be fine but the high salt and fat content is not good for them. But they are not a food that would be any good for them as they hold no nutritional benefit for their diets on a regular basis.
