Guinea Pig Is Not Eating Or Drinking - Tries To Chew Food But Can't - Vet Has Looked, But Cannot Find Problem! Looks Like Has No Strength In Jaw - Is Not In Pain And Being Syringe Fed - Which She Takes Could It Be A Slight Stroke?
Oh my goodness this is exactly what is happening to my guinea pig for the past 2 months. Have been syringe feeding for 2 months. Took to the vet 3 times - first time went under anaesthetic and had a scope, xray, trimming, and the works done. STILL not eating on her own. Picks up food very enthusiastically, tries to eat, then drops it. She tries so hard to eat but it's like she has no strength. I can't afford to keep bringing her to the vet to get her teeth trimmed. The vet is not sure what else to do other than keep doing the trimmings every 3-4 weeks, but it's costing me $300 per visit! Help!
