My cats fell into this category which was not surprising since they had been on a 100 percent dry food diet their entire lives and ranged in age from 2 -10 years at the time of the transition to a healthier diet. It took me several months to convince them that they are carnivores and need meat – and not in a dry, overly processed form that also includes far too many carbohydrates and too little water. It was a little rough, at times, since two of my cats get very crabby with their housemates when they are hungry. These boys were occasionally taken into a separate room during the transition period and fed some dry food because I do not like unrest in my home.
Hypothyroidism is a disorder of the thyroid gland, a small gland in the neck. Its primary function is to regulate the metabolism. With hypothyroidism, the thyroid is under active, so the metabolism is decreased. Hypothyroidism is rare in cats as opposed to hyperthyroidism (note the er) which is far more common. In fact, hypothyroidism is most likely to occur in a cat who is being treated for hyperthyroidism or after thyroid surgery. The treatment works too well and the thyroid goes from being overactive to being under active. Occasionally hypothyroidism may be seen in older cats, but again, it is rare.
