My gardeb is in So.Calif coastal.

Saw my cat staring at something yesterday afternoon.

Turned out to be a PURE WHITE SNAKE, about +- 3 feet long,
lurking under a rose bush. About 1-1/2" thick.

I called Animal Control, but snake was gone by the time they arrived.

They seemed dismissive of my (and my cat's; he was meowing and running
around in circles like crazy) concern. "Oh, it's just a garden snake;
we see them all the time", etc. I asked whether I should block up the
cat door, but they said snakes wouldn't go in there. ???

They probably meant "garter snake". Albino garter snakes are sold as
pets, as you can see he

Probably not a great danger to anything larger than a mouse
