My cats were meowing for food, so I went to check their dish. I saw there was still cat food from last night in the bowl, so I reached in with a fork to stir it up for them. It's canned food, so sometimes they mash it down and then can't really get to it. Well, as soon as I stirred it up I saw maggots all through it! I'm completely grossed out, but also confused. The screen door has been opened a lot in the last few days and it's been extremely hot lately, so I can understand a stray fly or two getting into the house, but do maggots actually develop that fast?? The cat food's only been sitting there since dinnertime yesterday! I'm totally sicked out. Should I switch to dry food? Is this an unusual exception because of the extreme heat maybe? The cat food isn't cheap, so I hate to dump whatever they don't eat each day, it would be a huge waste, because they do eat it all eventually, but I don't want maggots forming!! Yuck. Advice?
