For cats

Fassisi Thyrocontrol cat

Feline hyperthyroidism is a disorder of the hormonal system in cats, characterized by an overactivity of the thyroid gland (hyperthyroidism). It is now considered the most common hormonal (endocrine) disease in older cats over eight years of age.


With the Fassisi® ThyroControl Cat, you can determine within 10 minutes in practice whether the risk of potential thyroid overactivity (>40ng/ml TT4) exists in the cat.


Using the screening test, suspicion of hyperthyroidism can be quickly checked on-site, and further measures can be initiated directly in case of an elevated TT4 (total thyroxine) level.

You can purchase the Fassisi ThyroControl Cat from your veterinary medical wholesaler.
