The suspect or suspects also took a suitcase. Police said the owners told them Leo has some minor health issues.

The couple who owns Leo told KPIX that they were visiting San Francisco to celebrate their 12th anniversary.

“I felt like a part of my heart just fell in my stomach. And I thought, ‘He must be so scared. Where is he? Are they taking care of him?'” said owner Jacqueline Zavala-Lee. “I didn’t even notice the luggage was missing at first. I just started running around and screaming for Leo.”

Over the weekend, the distraught couple announced they were offering a $1,000 reward for Leo’s safe return.
