Hmmm... Have not noticed that at all. Most cat food cans have pop tops
these days and they stack just fine. I am torn on them though. Although
they are a nice concept, they don't always work like they should. I can
remember a few times when the can would not open. And if you do have to
resort to using a can opener on those tops, it can be very hard to do. I
had such a can at work once. Some kind of fruit to eat with my cottage
cheese. A guy that worked in the cafeteria tried to open it with his pocket
knife. That didn't work and he took it up to the cafeteria where he tried
to use the big can opener that they had on it. He eventually got it but
said that it was the toughest can he'd ever seen. And a pop top is how
Angela got that nasty cut on her finger a year or two ago. She still has
the scar from that.
