However, there are a couple of things that might make you think your guinea pig is getting fluffier:
* Growth: Guinea pigs are constantly growing until they reach adulthood around 6-8 months old. As they grow, their fur will become thicker and fuller.
* Grooming: If you're regularly brushing your guinea pig, it will help to remove dead fur and make the remaining coat look fluffier.
* Breed: Some guinea pig breeds have naturally thicker and fluffier coats than others. For example, Peruvian and Alpaca guinea pigs have long, flowing fur.
If you're noticing a change in your guinea pig's fur, it's important to watch for any other signs of illness, like loss of appetite, lethargy, or skin problems. If you're concerned, consult with a veterinarian.
