One of my oldest warrens has been looking very off color and today she is just sitting and not moving. I have given her worming powder in her food but still no sign of getting better. I have realised that whenever she gets to hot that she will start to pant and it looks hard to breath in her situation. Also I can see that her stomach is very swollen and she is very thin. She is still eating and drinking but is very ill i have found. Please help!!
