A man was taken into police custody on Monday night following a house fire in Strathmiglo in which two dogs died.
Firefighters from Glenrothes and Newburgh were dispatched to the blaze in the two-storey High Street property shortly after 2.30pm.
The end-terrace house was substantially damaged but no people were injured.
The blaze is being treated as suspicious and a forensic investigation is to be launched.
Police were interviewing the man and indicated they were not looking for anyone else in connection with the incident.
