Dental floss....

Apparently I didn't throw my floss in the garbage far enough and Oscar ate it....Travis saw him run away with it and couldn't catch him and couldn't find the floss anywhere. I know usually these things usually pass but what should I look for in the next few days to make sure it isn't stuck? Thanks guys!

Call your vet in the morning. They'll give you some advice, too. Things you need to look out for is change in stool - consitpation or diarrhea, your cat's belly getting tender, refusing to eat, and vomiting.

Otherwise keep checking the litter box and give Oscar some hairball paste to help him pass it if he can.
Obviously if you see any of it hanging out of his butt, don't pull - trim it before he gets to it and again, call the vet.

I'm just searching the house because I have a hard time believing he ate it without Travis not catching him in time. It was about 18 inches of floss so I really think there is no way he ate it....

I will call the vet in the morning and keep watching him. He's acting normal as of now
