Police swooped on a suspected factory at a house in Bradford - only to find the suspicious heat source was for two guinea pigs.
Officers arrived last week after the West Yorkshire Police helicopter detected a hotspot on the roof of the garage in Huddersfield Road, Odsal.
A hotspot is often a sign of specialist heating systems used to grow .
Police have apologised for any distress the raid caused to the guinea pigs' owner, 42-year-old Pam Hardcastle.
Mrs Hardcastle, a learning mentor at Bradford Moor primary school, said: "On Wednesday I'd gone to work and got a call from my mum who said you need to come home.
"The police came on the phone and said: 'We think you're growing in your garage.'
"I said: 'No, it's a heater to keep my guinea pigs warm because it's been so cold.'
