My husband and I got home from running errands a bit ago, and he noticed this weird thing in the pigs' cage. I have no clue what it is, and want to make sure it's not something I should be concerned about, though I have a feeling it is. It's a cloudy color, and was wet when we found it. When pinched between two fingers it feels like dry glue from a hot glue gun, or a ball of dried rubber cement; it's firm and holds it's shape, but it's also a little bit squishy. It was near the area where the boys sleep/play, if that helps at all. I took a couple pictures, though they aren't the best quality. If any of you have any idea what this could be I'd really appreciate some enlightenment. Thanks a ton!
