Felis catus – the domestic cat – is an amazing animal who delights and surprises even those of us who have spent years working with them. Among their many unique personality traits is their ability, highly evolved and adapted over thousands of years, to mask their pain when frightened, surprised, or otherwise stressed. It should be no surprise, then, that when your feline patients are in an unfamiliar environment, surrounded by sights, sounds, and smells they don’t recognize (such as a veterinary exam room), they will be inclined to mask their pain.

Cats in these situations also commonly experience fear, anxiety, and stress (FAS). FAS can cause a cat to mask their pain but could also result in behaviors easily mistaken for signs of pain. Partnering with your client, the cat owner, is essential to make an accurate diagnosis of pain in your feline patients.

Helping our feline patients with osteoarthritis (OA) starts at home, with our clients. As you are aware, cat owners are highly attuned to even small changes in their cat’s habits, personality, and idiosyncrasies that make them unique. Partner with your clients and teach them to screen for OA pain at home with a validated Cat OA Checklist produced by Zoetis. On this website, there are three simple screening steps that should only take your clients a few minutes to complete:

1. The first step utilizes animations to show healthy cat movement in performing several activities (e.g., climbing upstairs) compared to how cats move with joint disease. Your clients will be asked to check on the animations that are consistent with how their cat moves and that are suggestive of OA-related pain.
2. The next step evaluates, on a scale, the cat owner’s perception of their favorite feline’s emotional and physical well-being. Because OA is a chronic disease that can affect cats emotionally, this is an important step in connecting to the disease state.
3. The third, and final, step briefly summarizes, with yes/no questions, general behavior changes.

Once complete, clients can enter their email address to receive a copy of the checklist results. In some cases, clients will see the need to bring their cat into you for evaluation; others will need some encouragement to make an appointment. Consider recommending that your clients email the checklist results so you can identify those who might need to be seen.

To help prepare you for these kitties who will be coming to your office, Zoetis has created a website that provides you with resources such as helping to build cat owner awareness of feline pain, talk through the OA checklist they have completed, and feline orthopedic exam resources, including demonstration videos. This website contains a link to a printable version of the Cat OA Checklist that could be used, for example, with a client who has come into your office with their dog but has a cat at home that you haven’t seen in several years to encourage them to seek veterinary care for their feline companion.

It is important to remember that using Fear Free and Cat Friendly principles may mean that some cats who are coming to you to be evaluated for OA may require pharmaceutical help to remain calm. Keep in mind that some anxiolytic regimens may also produce analgesia and alter your exam findings. Objective diagnostic tools, such as orthopedic radiographs, are also an important part of the complete clinical evaluation.

Orthopedic exams and diagnosing OA in cats are yet more reminders that cats are not small dogs! As you partner with your cat-owning clients by asking them to screen their cats in the environment where they are most likely to show signs of OA, you will be better able to diagnose your arthritic feline patients. This partnership will greatly enhance your reputation amongst your clients who will see you as a trusted advisor to their beloved and treasured cat companion.
