WD-40 Saved My Cat

My cat used to go right inside the crate when I needed to take her on trips. When the door began squeaking, she would run. I couldn't get her in the crate until WD-40 fixed the squeak. WD-40 silenced the squeak.

Step 1: I got my WD-40
Step 2: I removed the cap
Step 3: I applied WD-40 to the squeaky metal parts
Step 4: I tried it out.
