“On Sunday night our sweet kitty, Willow, wouldn’t put her back leg down. We rushed her to Horn Lake Animal Hospital where they immediately did an X-ray and we were told her femur was badly broken.
Willow spent two days there prior to surgery and 2 post surgery. She’s now home and recovering well. I will forever be grateful for the care shown to our sweet girl and the courtesy of the staff. Would definitely return in the future.”
