If you see a massive white snake slithering around in Thousand Oaks it's not your Labor Day Weekend hangover giving you flashbacks.

An exotic albino cobra was on the loose in the Ventura County community today, and authorities were warning residents to call 911 if they spot it. The L.A. County Department of Animal Care and Control is on the hunt for the  albino monocled cobra because it has a contract to serve Thousand Oaks, officials said.

The snakes are “venomous,” said Animal Care and Control spokeswoman Lara Arsinian, but …

 … more than that, their bites can be deadly if left untreated. A county spokesman said authorities have “identified a source of anti-venin at the San Diego Zoo” just in case.

A dog was reportedly bitten by the snake yesterday. Arsinian said the owner notified authorities that the snake was still out there somewhere roughly at 10:30 this morning. The resident also took a photo (above).

The white rarity was last seen in the 1300 block of Rancho Lane in Thousand Oaks, county officials said. Was it someone's pet? “We can't speculate on that right now,” Arsinian told us.

According to a statement:

The County of Los Angeles Department of Animal Care and Control is advising residents in the area to not approach or handle the snake in any way. It is vitally important for families to closely supervise children and instruct them to avoid any snakes, as well as playing in and around animal burrows, pipes and culverts where snakes may seek refuge.

If you see this snake, please CALL 911 and alert the Department of Animal Care and Control or the California Department of Fish and Wildlife immediately.

Authorities say the monocled cobra, which calls Southeast Asia home and can grow to 7 feet or so, is especially active in the morning and evening, when it's cooler.

They normally prey on rodents and amphibians but they will take a bite out of you if provoked, authorities said.

[Added at 1:18 p.m.]: The dog survived and was in “critical condition” after the owner took it to be treated, Arsinian said.
