"between 10 PM Saturday evening and 5 PM Sunday"

It is an all night theory.

This kept happening to our neighbor and us. Someone mentioned rodents (including rabbits) and setting up live traps proved both of us correct. They are drawn to the heat is what I was told, and love the wire to chew on. If possible, lift the wires up off the ground...maybe spray the ground with ammonia as a deterrent. Also, if your vehicle is parked outside all the time, check for chewing on wires under the hood. They like chewing on plastic/vinyl as we just recently learned.

Had the same problem, found out it was squirrels in my case.

Just happened to us too but we only had one cut and thought it was from the sharp leaves on the holly blowing in the wind. Changed that string and no problem last night. If it happens again I guess it will be a critter. If it was caused by a person all our lights would have been out not just one string.

Since it was a person and not a rodent (of the four legged kind). Do you have any enemies? Sorry for your experience, some people are just plain mean.

Just had the second string of wires cut in three days. First time it was two of three wires. Second time it was three of three wires. Cut clean on a diagonal. These are in the bushes behind the house, facing a Pennecamp village access road. Nothing cut in the front yet, facing a local street. I am going to put out one more light string in that spot, to see what happens.

You have a rodent making a clean cut. On your lights. No person would do that in your bushes in back of your house.

Ours was also behind bushes in the front of the house and a clean 3 wire cut at an angle
Lights are turned off at 10PM

Few happen to be Humans

:loco:
Hahaha...I'm originally a city girl, so I don't think of 4 legged rats automatically, but reading the other posts, apparently it could be. What a bummer. So sorry some people are having their fa-la-la messed with.

Same thing happened to me in Pennecamp ������. I believe it was the squirrel that loves to tease my cat. I wrapped the cords with duct tape and sprayed WD40 and no more problems ������

Those rodent teeth are pretty sharp and really can do a clean cut. This comes from experience. I found that elevating the wires took care of the problem.

We had lots of problems with squirrels chewing through overhead cable lines. It's very common.

Cut wires
 

The cut was at my neighbors and they are well liked.

Big assumption!
