Four cats in lunch bag ~ at bedtime two were near the top in J shape. This morning those 2 were pupa and another keeps crawling around near top of bag, but not done the J thing. Other one is on the bottom of bag and is not well; two of smaller ones still in plastic container look the same. They look smaller and are not eating although there is movement in their body like they need to throw up. I've put fresh leaves by them and moved the larger, well cats to bag so I can keep check on these 3 sick ones. Is there anything I can do?
