Storm has been having a loose stool for 2 days now, he is eating fine, activity level still the same he is drinking water etc. Well he just Pooped and Peed where he was because he couldn't make it to the Potty Pad in time and when I was cleaning it up I noticed a few White mucus looking worms moving back and forth

in his poop.
Has anyone else ever seen this? I'm taking him to the vet 1st thing in the morning.
