A "Custom Pet" is a one-of-a-kind pet which is owned by only one player on the site. There are many different customs on CS and every one of them looks different. Often it is a design that is special to the owner, like a fursona or character design they made themselves.
Customs are awarded in special circumstances only, for example they are given to staff members to reward them for helping out the site.
Question: "Can I have a custom pet? How can I get one?"
No, you can't have a custom pet.
You can't make one for us to upload, and you can't request us to make one for you. They are only given out in special circumstances to special people, for example to staff who have earned it by helping out the site.
We don't sell custom pets.
Please do not send staff a request for a custom pet, you will not get one.
