The Origin of Rex Guinea Pigs

Tracing back to South America, guinea pigs, or cavies, have been domesticated for thousands of years. However, the rex guinea pig breed is a relatively recent addition to the guinea pig family.

A rex guinea pig's diet should be rich in fiber and include a continuous supply of fresh hay.

Their fur stands up in a delightful array of spikes, unlike the teddy guinea pig, which boast a softer, dense coat that resembles a cuddly teddy bear. Both breeds have forward growing hair, but the Rex's coat is rougher to the touch, while the Teddy's is velvety, making them both irresistible to pet lovers.

Teddy guinea pig, while similar in size to their Rex counterpart, has a different grooming requirement. They benefit from regular brushing with a soft-bristled brush to keep their fur in tip-top shape. Rex guinea pig, on the other hand, have a more low-maintenance coat that doesn't mat easily. However, both breeds require their nails to be trimmed regularly to prevent overgrowth and discomfort. It's important to use a dedicated guinea pig's nails clipper, which can be found at most pet stores, to ensure a safe and comfortable trim.
