I was visiting my parents today and their cat Kirby had something all over his back. My mom had no idea what it could be. I tried rinsing it out but it was very gummy and that didn't do anything. He eventually got mad about being held in the sink so I let him go. A while later, I gave him a bath in the laundry room sink using soap and that didn't do anything either. Finally I just decided to cut out all of the stuff that was in his fur because I honestly think it was a glue of some kind. He looks stupid now, but it's mostly out of his fur. He's the sweetest cat ever and was very mad and was actually biting me, so I didn't force him into a third trimming session.
