I’m really sorry for your loss. I hope you take all the time you need to recover, and remember that good cat.
I switched to the store brand. Ziplock name brand bags got too hard to open.
I have five cats, and it’s pretty easy actually. I just tape all the holes in the pizza box shut, and weigh the lid down so they can’t open it. Then I hold my plate at shoulder height, and eat while walking aimlessly about my house. Seriously, it’s not a big deal. (Do we do /s tags here?)
Danger is the Siamese.
