Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before.Different experts come online at various times; I just came online, read about your situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner. If you would still like assistance, can you tell me:
How long ago did he eat these diapers?
Any retching, gagging, lip licking, drooling, or vomiting?
Can he eat and drink? Can he keep any water down?
Are his gums nice and pink (not white/pale)? Moist or sticky?
If you press on his belly, doe she have any tensing, tenderness, discomfort, or pain?
When did he last pass stool?
Is he straining?
