Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
How long has he been showing signs?
Can he keep any water down?
Are his gums nice and pink (not white/pale)? Moist or sticky?
If you press on his belly, does he have any tensing, tenderness, discomfort, or pain?
Any changes to his thirst, urination or stools?
Could he have eaten anything he should not have (ie bones, stones, socks, toys, chemicals, human meds, etc)?
Did you mean cedar shavings?
What plants does he specifically have access to?
