porkysmamma that it's really situational. Linus is an older bully so he doesn't eat too fast but he has really bad respiratory allergies and I noticed they were getting REALLY bad after he ate. This has improved that a lot because his head isn't down the entire time. Also, we feed really tiny kibbles - it's great food but I do not like the kibble size - and he is able to get everything in the bowl WITHOUT causing a huge mess!
So far, so good! I am going to clean my baseboards tomorrow and hopefully they will stay clean with the new feeder!
