Customer Question

We have breed guinea pigs for some time. I am a pharmacist and understand when an animal is sick. We have had this male Guinea Pig for about 3 months. He does not move much and only eats apples and oranges! no carrots, spring mix or veggies. I fear he is losing weight, a sure sign of not too long a life?

My name is ***** ***** I have been a Vet tech for 30+ years with interest in Small animals and exotics.

Does he eat his pellets at all?

Does he eat any Grass hays?

Do you give an actual Vitamin C supplement?

Have you tried any supplemental feeding?

The lethargy he is showing may be due to his poor diet choices. It could easily be a vitamin deficiency, or could be a thyroid issue. I would start him on a separate Vitamin C supplement. You can crush the chewable Vitamin C tablets for humans. I would give 150 mg daily. The C as you know is water soluble so it should not be a problem. I would also start him on Critical care by Oxbow as a supplemental feeding to try and get some balance into his diet. A fecal sample done by the Vet would be wise as well as some blood work to rule out a thyroid or other medical issue. Hopefully with the boost in Vitamin C and Supplemental feeding, he will pick up. The Vet may be able to give an appetite stimulant. I can suggest a natuarl appetite stimulant which is Royal Jelly. It is what is Fed to the Queen Bee and has been used in cases like this. Just open the capsule and feed or dust over the food.
