When our 1.5-yr old siamese cat was in heat 2 months ago, we put her in the same room as the same father of her first litter. After 2 days, we let her out of the room but not outside of our house. A few hours ago, she gave birth to her second litter. We were expecting that the kittens will look like the first ones but they didn't. Could she have mated with another cat before we locked her up?
