Prince George, Princess Charlotte and Prince Louis "forget" an important home task amid their chores, Prince William has claimed.
The Prince of Wales, 41, took a trip to the Midlands on Thursday where he visited Woodgate Valley Urban Farm in Birmingham, a city farm dedicated to supporting children experiencing mental health challenges.
Prince William shared a glimpse inside his family life with Princess Kate, 42, and his three children, Prince George, 10, Princess Charlotte, eight, and Prince Louis, six.
While stroking a peaceful guinea pig with a comb, the Prince of Wales revealed that his family has pet guinea pigs at their home Adelaide Cottage.

However, there is a responsible task to complete that is often neglected by his children.
Prince William shared an insight into his family life while chatting with the children.
He said: "I spend my life cleaning out the guinea pig cage because the children forget to do it."
Stroking a guinea pig called Snowflake, William commented that the pets looked "well-loved" and "extremely cosy".

While visiting the facility, Prince William met Sue Hawkswood, the project manager, who created the farm to help children with special needs, and the prince described the initiative as a "wonderful little tranquil space".
Prince William also visited the sheep enclosure. As he bent down to stroke one of the animals he chatted to Hawkswood's son, Alfie.
The prince told Alfie that he thought it was "very important" to talk to sheep and ask them how they are feeling.
The royal also headed down to the chicken coop where the prince revealed he had chickens that loved eating dried fruit.

Hawkswood also admitted that some of the children who visit the farm have been unable to access education and have such poor mental health that they are self-harming or refuse to leave their homes.
Currently funded by the National Lottery, the farm supports small groups currently out of education as well as sibling groups from a local children’s hospice.
Earlier that day, Prince William surprised a 12-year-old pupil at his school in Sandwell, much to the boy's delight.
He decided to visit St Michael's Church of England High School in Rowley Regis. Student Freddie Hadley previously invited the prince to the school on World Mental Health Day in October.
