Veterinary Journey Saves 10-Year-Old Cat’s High-Five Habit

A 10-year-old orange cat named Mars from New Jersey was losing the ability to walk, jump and give high-fives because a pituitary tumor was producing excess growth hormone. The tumor also caused severe diabetes, an enlarged heart and neurological signs. After medication and radiation failed to shrink the tumor, his owner Yisi traveled to the Veterinary Referral Center of Central Oregon for a rare transsphenoidal hypophysectomy, a surgery that removes the pituitary gland.
The VRCCO team spent two months preparing, using cadaver specimens, 3-D imaging and custom templates from CT scans. The operation required a tiny opening in the skull and a specialized camera to reach the gland. Patients who undergo this procedure can experience dangerous sodium changes and usually need lifelong hormone and thyroid support.
Following the surgery, Mars’ insulin needs returned to a normal range and he regained the ability to jump onto stools and give high-fives again. Yisi praised the team’s patience, organization and gentle care, and the hospital’s medical-travel program helped coordinate their stay.
Key takeaways
- Mars’ pituitary tumor caused severe diabetes and neurological problems.
- A transsphenoidal hypophysectomy was performed at VRCCO after other treatments failed.
- The surgery required precise preparation and specialized equipment.
- Post-operative care included monitoring sodium levels and hormone replacement.
- After surgery, Mars’ insulin requirement normalized and he could jump and high-five again.
