My cats are just as bad, if not worse, than any dog I have ever had. I have never spent as much time and energy stopping another living being from eating things as the ones I currently have.
And it's not like they're being underfed! They have constant access to kibble, and are given fresh wet food twice a day. They're even given extra wet food than what they really need just in case someone's super hungry that feeding session!
It's gotten to the point I can't even let them see bags of chips. They don't even actually want the chips, they just know it's food they haven't smelled in the past .5 seconds, so they wanna open the bag!
And then there's when I add dangerous(for cats) spices. Onion? Garlic? They want it all the more. I swear, if I put onion and garlic on a plugged-in charging cable, they'd die happily, cause those are the top three things the little suicide risks want!
