Christina became a member of the A Cat Clinic team in March, 2017.  She is mainly at the front desk, but will occasionally help out with the patients.  Her prior animal experience includes several years doing grooming. As a child, she was not allowed to have a cat, so that was the first pet she got when she became an adult.  She says, “As every cat owner knows, nobody owns a cat!”  Christina has three young children, and when she has a free moment enjoys reading.  Sadly, she does not currently have any pets, so she’ll just have to get her fill here at the clinic!
