  • Mushroom toxicity can run the gamut from irritating illness to severe toxicity to death. The species of mushroom and amount ingested determine the severity of the toxicity. Since mushrooms are difficult to identify, it is best to discourage your pet from eating any mushrooms growing in the wild. In the event of mushroom ingestion, prompt treatment is critical to successful treatment. Pet owners need to be alert to the possibility of mushroom toxicity and work to eliminate their pet’s access to mushrooms.

  • Picky eaters are often created by their humans offering too much variety of food. Cats can become picky eaters for medical reasons that need to be determined by your veterinarian. It is safe for an otherwise healthy cat to not eat for a few days; beyond this however, they can develop a possibly fatal condition called hepatic lipidosis. To decrease pickiness, having food available for only 30 minutes4-5 times a day can be beneficial. Human food should not be used as a diet as it will lead to nutrient deficiencies. Certain foods are okay to mix with cat food to make them more appealing but check with veterinarian before including these in your dog’s diet. Many cats work on their own schedule and prefer to eat very small amounts frequently (grazing).
