I was just cleaning the floor when i noticed the area around Arthur's cage was covered with blood. At first i thought it might be urine as he had a red apple last night and we all know how bunny pee changes depending on what they eat but it was definately blood coming from his front paw. I had a look and it seems that one of his nails is missing (the one on the inside of the paw). I have bathed it and dried it but i really cant afford an emergency vet (always on a sunday!). He doesn't seem to be in any pain and is walking on it happily without any sign of a limp. I have confined him to his bed/cage on a clean, dry towel and he's happily munching. Is there anything else i should do? What are the signs of infection (i think i know obviously but you can never be too sure)?
