The number of cats with suspected or treated hyperthyroidism grew over the 3-year period (2013-2015). These patients received a variety of tests, hormone products and occasionally, Hills Y/D prescription diet. Our projections estimate the feline hyperthyroid treatment market at  $5-10 million in 2015.

Our rigorously qualified sample was triangulated with other data sources for validation to ensure our projections are reliable within +/- 5% level of accuracy. Triangulation was performed from a medical case database to project the size of the clinical Feline Thyroid Hormone Market (approximately $10 million). From our database, we selected 588 pre-qualified clinics with complete invoices for the 36 month period (2013-2015),containing 1296 small animal general practice veterinarians (universe of 57, 300) distributed throughout the US to obtain a weighted projection factor.

The number of active feline patients (at least one invoice/year):

POPULATION OF ACTIVE FELINES IN GENERAL PRACTICE CLINICS IN CONTINENTAL USA

These active feline patients come in to the clinic on average 2.65 times per year and so the projected number of treatments is 53 million. A treatment is defined as at least one clinic invoice in a day.

The frequency of actual clinic visits invoiced for these active feline patients indicates that 28% of the cats come in annually, 34% come in every other year and 12% come in every three years, while 24%  turn over annually, either due to death or relocation. So out of the 20.2 million cats, only 5.66 million come in every year, while nearly half come in every two or three years.  Some 4.8 million are newly treated cats from relocation or kittens.

The number of suspected or treated hyperthyroid felines:

SUBPOPULATION OF TESTED OR TREATED HYPERTHYROID FELINES FROM ABOVE POPULATION

Cats with suspected or treated hyperthyroidism came in 4.3 times /year, once for testing and 3.3 times for treatment with a hormone replacement.

The number of felines that received a test but no treatment:

SUBPOPULATION OF ONLY TESTED HYPERTHYROID FELINES FROM ABOVE SUBPOPULATION

The number of felines that received treatment only:

​SUBPOPULATION OF TREATED HYPERTHYROID FELINES FROM ABOVE SUBPOPULATION

These cats came in an average of 3.3 times/year for hormonal replacement therapy or 110 total days of therapy.

SUBPOPULATION OF ONLY TESTED AND TREATED HYPERTHYROID FELINES FROM ABOVE SUBPOPULATION

The number of treated hyperthyroid feline patients is increasing.

These patients received a variety of tests, hormone products and on rare occasions (average of 9,662 patients per year) Hills Y/D prescription diet.

Over this 3-year period (2013-2015) there was an average of 187,300 unique cats that received treatment/year, with or without a test.  These cats received an average of 623,500 hormonal replacement products/year. The number of clinic visits/cat was 3.3 times per year or replacement therapy for 110 days. So this means 68.6 million treatment days, at a cost of $0.1-0.12 per day (an average of 10 mg per day for a 10 lb cat) equals an $8.2 million market, which is about the size of the cat hormonal market.

Another way to look at this data is that of the  187,300 unique cats that received treatment/year, 23% were newly diagnosed and were given an average of 190 of days of therapy (as for DM) and 77% were  existing hyperthyroid cats from prior years and were redispensed an average of 330 days of therapy during the year, which is an average of about 298 therapy days This means that there were 55,726,000 days of therapy, which at an average of $0.11 clinic cost per day gives a hormonal replacement market of $6.9 million, which is about the size of the hyperthyroid products (methimazole and felimazole) market.
