A man is currently assisting investigators with their enquiries in relation to an incident in Cranbourne last night.
Police have been told the woman parked her car in the carpark of a lost dog's home on Thompsons Road when the armed offender approached her about 11.30pm.
The man allegedly pointed a firearm at the woman, who works at the home, before he walked her into the animal welfare property and tied her up.
He asked the victim where the cats were before he left the room and didn't return.
The woman, who wasn't physically injured, was able to free herself and raised the alarm.
Casey Crime Investigation Unit detectives are currently interviewing a 44-year-old Langwarrin man.
Anyone with information is urged to call Crime Stoppers on 1800 333 000 or to submit a confidential report can log onto www.crimestoppersvic.com.au.
