Ovarian tumors are uncommon and only occur in the intact queen (Klein 2001). They are typically unilateral, metastasis is uncommon, and they become quite large before they are detected. Some ovarian tumors will secrete estrogen, resulting in a prolonged estrus. Unlike in the bitch, hyperestrogenism in the cat is not likely to result in alopecia (Mecklenburg et al. 2009).

Most of the ovarian tumors result in non‐specific clinical and behavioral signs. These signs include a distended abdomen due to tumor size or ascites. The queen may also vomit, be anorectic, appear constipated, urinate frequently, have an increased respiratory rate, or show signs of discomfort when lying down due to the physical size of the tumor putting pressure on other organs.
