A tube of cable ties is an inexpensive investment in security -- securing pet carrier doors, holding up plastic snow fence are among the many uses.

Pros: Lock tight

Cons: Keep pocketknife handy to release

I use these ties on cruelty cases to hold carriers and crates together instead of the nuts and bolts. They are quick and easy to connect.

Pros: great for emergencies

Cons: one time use

I use these for the dog pens to secure the doors. I have found a few escape artist. The door is not secure until these are in place.

Pros: repair, hold things together

Cons: none

We use them for securing pens, tarps, cages, and all sorts of other things.

Pros: Versatile

Cons: None

these work well for extra safety when trying to keep the pet in the cage.

Pros: everything

Cons: none
