Here's why:
* Breathing problems in guinea pigs can be a sign of many issues, some very serious (like pneumonia, lung infections, or even heart problems).
* Not eating is a major red flag in guinea pigs. They need to eat constantly to maintain their digestive system.
Please take your guinea pig to a veterinarian as soon as possible. The sooner they receive treatment, the better the chances of a full recovery.
In the meantime, you can try to keep your guinea pig calm and comfortable:
* Provide a quiet, draft-free environment.
* Make sure they have fresh water.
* Keep them warm.
I hope your guinea pig gets better soon.
