Small sized cats are just under 4" long. Choose the pattern and eye color. If you'd like to request non-standard colors (something different than the patterns in the pictures), choose non-standard colors and enter your requested colors in the personalization field. The option for a personalized custom cat requires that you send pictures of the cat you'd like matched via the messaging system. Calico cats come with black eyes. Please reach out with any questions! This product is made to order using a plant based plastic on a 3d printer. 3D printing is an additive process, meaning you may notice small imperfections or layer lines. Rather than seeing this as a defect, we like to think of this as adding to the uniqueness of your product. While we make every effort to ensure our products are durable and will not break, we do not recommend them for small children as there may be small parts that are considered a choking hazard. Please do not put this product in the dishwasher or leave it in direct sunlight in high temperature areas (for example, a hot car in the summer). The plastic used to make your product is not designed to withstand high temperatures and doing so may cause it to warp or melt. I am a licensed seller of Zou3d designs.
