For myself, the owner of Chris's Squirrels and More, I am also like many of you, an animal care giver specializing in the rehabilitation of squirrels. These little spring hooks are a god send for me in my clinic. They have more than 101 uses. I use these things for everything! I absolutely love them.
These finger loop springs are ideal for keeping any cage closed. They can be put anywhere and will keep your cage securely locked. They are easy to move from one part of a cage to another, they are actually strong enough to hang a small cage to a larger cage when using 3 - 4 clips. Measure 3 1/2" in length.
