Hills Science Diet Adult Small & Toy Breed recalled due to potential Salmonella contamination
In June 2014, Hill's Pet Nutrition of Topeka, Kansas, US, announced a voluntary recall of 62 bags of Science Diet Adult Small & Toy Breed dry dog food. The recall was due to potential Salmonella contamination. The affected product was distributed to 17 veterinary clinics and pet stores in California, Hawaii, and Nevada between April 24 and May 13, 2014. The company stated that the product was accidentally released during a routine inventory reconciliation.
The recall only affected 15.5-pound bags of the Science Diet Adult Small & Toy Breed dry dog food with the SKU code 9097 and the \"Best Before\" date and production code 08 2015 M094. Hill's Pet Nutrition contacted all 17 customers who received the potentially contaminated product and offered to collect any unused portions and provide full refunds. No illnesses related to the product had been reported at the time of the recall.
It is important to note that this voluntary recall did not impact any Science Diet Adult Small and Toy Breed products with different "Best Before" dates or any other Science Diet products. Consumers who purchased the specific recalled product were advised to discontinue use immediately and contact Hill's Pet Nutrition for further instructions and a refund.
In 2019, there was another recall of Hill's Science Diet products due to potentially elevated levels of Vitamin D, which could cause health issues in dogs. The affected products included various sizes of Hill's Science Diet Adult Chicken & Barley Entrée Dog Food, Hill's Science Diet Puppy Chicken & Barley Entrée, and Hill's Science Diet Adult 7+ Small & Toy Breed Chicken & Barley Entrée Dog Food.

Hills Prescription Diet K/D linked to constipation in cats
While Hill's Science Diet products are formulated after extensive research and clinical studies to cater to the nutritional requirements of pets with certain health conditions, some consumers have reported adverse effects on their pets' health.
In the case of Hill's Prescription Diet K/D, a cat owner reported that their 12-year-old cat, Snowball, who was diagnosed with early kidney disease, experienced constipation after being put on a strict diet of K/D dry cat food. The veterinary clinic recommended including some K/D moist food in Snowball's diet, which helped only to a certain extent. This raises the question of whether the issue could be due to a lack of fibre in the cat's diet.
Another cat owner reported that their cat developed pancreatitis and diabetes and had to be switched from dry food to Hills ID wet food, only to be later diagnosed with a chicken allergy.
In addition, some reviews mention that their cats fell sick, experienced vomiting and weight loss, and even passed away after consuming Hill's Prescription Diet products. However, it is important to note that these reviews do not specify whether the issues were linked to constipation or the K/D formula specifically.
While Hill's Pet Nutrition conducts extensive research and clinical studies to formulate their products, it is always advisable to closely monitor your cat's health and consult your veterinarian for guidance on dietary recommendations and approval.

It is important to note that individual responses to any diet can vary, and underlying health conditions or other factors may contribute to adverse reactions.
