I make enclosures, cages, shelters for all kinds of pets. I use wood, plastic, metal, glass or a combination of materials depending on what's needed. These are just over 3 foot by 3 foot (9.75 sq ft) so are perfect for Guinea pigs because they require more space than most small pets. They are 18" high so they cant jump out. It has a wire section mounted inside to hold water bottles and such. If you have other pets you want to keep out (cats or dogs) I can add a top. They are lightweight and easy to clean and they can be painted. Something this size from a pet store would cost three times as much or more. If you're interested you can reach me by email here, call or text four2three five0five 5two7eight between 9am and 9pm. Thanks
