Firefighters are investigating what caused two cars to catch fire outside an Altamonte Springs home, where four pet birds were killed.

One of the seven people inside the home saw the two cars on fire in the driveway of the Mockingbird Lane home around 4 a.m. Wednesday.

The fire spread to the garage, but crews were able to prevent it from causing major damage to the house.

No one was injured in the fire, but the cars were destroyed and the garage was gutted.  Three dogs were able to escape the fire, but four parakeets died.

The cause of the fire is under investigation.
