Hello @Xenia1802 and welcome to TrustedHousesitters and to the Community Forum 
To confirm you will need to create separate listings for both your homeowner profile and your sitter profile.
You can also add your TrustedHousesitters profile on to your profile on here by following the attached link, should you wish. This will then enable others to offer you helpful advice and feedback and will also give your listing more coverage! 
If you are unsure how to do this or if you have any questions, do not hesitate to ask, we are all more than happy to help.
Do you have a photo of your kitty that you can share on here? We would love to see! 
Whereabouts will you be hoping to travel to and house sit?
