Why is my guinea pig not eating, drooling, and losing weight?

Updated on September 23rd, 2025

Pet's info: Other | Unknown - Other | Male | 1.54 lbs

I have a guinea pig which i think is poorly. I have separated him from his cage mate and put him in his own cage. I then noticed that he was not eating so i fed him some veg which was cucumber, carrot, and tomato, and he had eaten them all by this morning. I have also noticed that he has a very wet patch underneath his chin and was wondering what this could be. I weighed him Tuesday and he was 700g then weighed him again yesterday and he was 650g so lost 50g over night.

Good morning! Yes, that sounds like a worry for sure, although I'm glad he did eat some food overnight. The wet patch could be drool; perhaps he is having trouble with his teeth?

It was a smart idea to weigh him, and this proves that he is likely dehydrated, having lost a fair bit of weight overnight.

Would you be able to find a vet that is comfortable working with guinea pigs today? It sounds like Buzz needs an exam, to sort out what is going on. Good luck!
