Just one more thing to add to the list of "dont' leave unattended".......
The rubber caps, or "condoms" as many people call them.
I have a cat that actually STEALS anything that is plastic or rubber. And if she can run off with it, she eats it. We've caught her with plastic wrappers, rubber bands, you name it.
She had a very unfortunate incident with a "Plink" late one evening and I was sure she was a goner. (If you don't know what a Plink is, google it.......) Yet after much drooling, frothing at the mouth, flushing her mouth out with water over and over......she survived, and STILL she tries to steal things.
I know in my heart that if given the opportunity, she would steal these little rubber caps and try to eat them. I fear it would kill her.
So we're VERY careful to keep them contained in something with a lid, and up out of her sneaky little reach.
