Human Foods That Are Toxic To Cats

There are some foods that are toxic to cats, and as cat owners, we are sometimes tempted to share a bit of food off of our plates,or enjoy making homemade meals for our cats, so we should be aware of possible foods that could make our cats sick. Although making a meal out of fresh food for your cat can be both enjoyable and incorporated into a healthy balanced diet,we must keep in mind that our cat's digestive system is very differnt from ours and there are some food that will not only make them very sick, but can cause fatality if consumed over time.

Green Tomatoes,Raw Potatoes

Both green tomatoes and raw potatoes contain solanine, which is a glycoalkaloid poison. Glycoalkaloid solanine can cause gastrointestinal symptoms in cats such as; vomiting, adnominal pain, diarrhea.

Although we're used to seeing cute kittens being feed milk on television, the truth is many cats are lactose intolerant. Being lactose intolerant myself, I know the stomach discomfort that drinking milk can cause. Now your cat might be one of the lucking few that aren't lactose intolerant, but why take the chance? Your cat doesn't need milk; they love a fresh bowl of water minus the stomach cramps.
