Feline Upper Respiratory Infection Clinical Trial

Raintree Animal Hospital is conducting a clinical trial for cats with upper respiratory infections. Cats must be at least 12 weeks old, weigh at least 1.9 pounds, and currently exhibit signs of an upper respiratory infection. All breeds and sexes accepted. This is a placebo-based trial for a liquid medication given once daily for 7 days. Qualified candidates will receive exams, lab work, and medication at NO CHARGE and will receive a monetary hospital credit for completion of this 13-day trial to use toward any additional service. For more information and to see if your pet qualifies, please call us at 970-482-1987.

Feline Diabetes Clinical Trial

Have a cat with diabetes or clinical signs suspicious of diabetes (excessive thirst, excessive urination, tiredness, weight loss despite a normal or increased appetite)?
Let’s work together to fight for independence from daily insulin injections! Ask about participation in a FREE* investigational trial that may lead to an oral treatment option for cats with diabetes.
