Short answers are annoying, and hard to take seriously, but what i hate is when they just say 'No'.
I had a cat that, one day i went into the basement to find that it had evicerated a bag of fish flakes i had, made a huge mess, and consumed a large portion of it.
The bag diddnt have an ingredient label on it, so im not really sure what was in it, but as far as i know, the cat was fine.
I know pellets are different, and in the case of bloodworms, there could be real health issues involved, but when in doubt, look it up on wikipedia, or even webMD.
