I found a weird pile of foam, looks like it may be a vomit? This is the 2nd pile to show up in my yard in a week, the first is mostly gone (blending in with mulch at this point). Does anyone know what this might be? This second round is on top of my coral bells! So I want to know if it\'s vomit, should I wash it off, etc. I haven\'t used any animal deterrents besides sluggo for my hostas, but I haven\'t put any of that down in weeks. Simply can\'t think what it is that an animal has eaten that it\'s throwing up. We do get deer, lots of chipmunks & squirrels & I recently found a shrew in my garden (surely that little dude isn\'t doing this!) Thanks for any help!
