One of my cats found a ribbon someone got on a gift and forgot to throw away (i make it a rule to throw out ribbons and twist ties on sight specifically because this cat will seek them out to nibble), and bit off and ate the tip of it, maybe an inch or so. Later, half of it ended up hanging out his rear before he passed it completely. Cue me getting rather panicked because it looked, at the time, like he’d eaten a whole ribbon rather than a tiny piece, and to my understanding, doing that can be incredibly bad for a cat due to the potential for it to get stuck or damage their gut. To make matters worse, at the time I was a teenager in a suburban neighborhood with no ability to drive and my parents were away on an errand, so I had to wait for any chance to get him to a vet. Then he ended up passing it before they got back and at the same time I found the rest of the ribbon with only the tip nibbled off, so it turned out fine, but it was a scary few minutes.
