Helping piggies live their lives to the fullest!

Founding Story

Initially, GuineaDad started as an Instagram account (@guineadad) to show off our three piggy princesses. If you look right back to the beginning, you will see our pictures were solely to provide fun with Peanut, Tofu, and Dumpling.

Sadly, Tofu soon got bacterial conjunctivitis and Si visited the shops and various online sites to find the best products from well-known brands and DIY solutions. As it goes, Si stumbled upon the sad truth of the market; products for small animals are sub-par (to say the least!) because they aren't as profitable as the ‘mainstream’ pets such as cats and dogs. Myself, as well as many others, were forced into DIY solutions but a distinct lack of resources made this incredibly tough.

As a result of this experience, Si and Sean vowed to dedicate their time to producing high-quality products for small animals to ensure their well-being for years to come!

Future Vision

Many small animal products are produced with sub-par quality and/or care because some people consider them ‘less important’ than ‘real pets’ like dogs and cats. However, this cannot be further from the reality. The small animals deserve the same full attention to live happy and healthy lives. We plan to expand our product line not only for guinea pigs, but for small animals everywhere.

Our Guinea Pigs

Tofu aka City Girl

Tofu is the youngest and biggest girl of the three. She loves to eat, poop and sleep. Her bacterial conjunctivitis was the reason we created GuineaDad Fleece Liner.

Peanut aka The Alpha

Peanut is a beautiful girl who first joined GuineaDad’s family.
She is very athletic and bossy. She rock climbs(?) at her spare time - for carrots.

Dumpling aka Drooler

Dumpling was the last to join the herd and was adopted from Critter Corral, the guinea pig rescue center at Illinois. She is a true food fighter. There is no such veggie that she would not eat. She occasionally drools green juice while eating veggies.
