Ah, I see. Well I guess it doesn't rule it out but it is pretty good evidence that maybe it's not the cause of their death. I am so anal about keeping the cats off my tanks but I guess it's not that big of a deal. I wish I knew why the died and have been wracking my head.
Now that I think of it, the only thing I have changed is where I get their crickets from.
Poor little guys.
I did not think about the necropsy but that would have been a possibility but I have already buried them down by the creek. I could dig them back up but with the heat here, I think they may be a bit decomposed. I keep a few preserved specimens (I'm a zoology student) but since I considered them pets, I buried them instead.
