Unhealthy Foods for our Pets
We have all set up our homes to keep young children secure, but what about our house pets? Same as for kids, many non-edible and edible things may exist in or around your home and can put our pets in danger. Knowing about these dangers can assist us in making our home a safer environment for our pets.
Many pet owners become so close with their pets they almost seem human. For the most part, this is harmless. But, some food and drink items that we consider tasty treats may be dangerous for our pets. For example, several fruits, vegetables, nuts, seeds, condiments, additives, and drugs are toxic to domestic pets. Some harm only dogs, others only cats, and several are poisonous to both. If the animal ingests anything from the list below, even if there are no symptoms, the pet owner should contact their veterinarian right away. Furthermore, if the owner can estimate how much of the product the animal has consumed, that would be helpful. We may have overlooked some products in the tables below. If the owner has any questions regarding a product that isn’t listed in the table, they should consult their veterinarian for more information.
