Hello @Shireen and welcome to the Community Forum 
You certainly live in a great location, we recently spent a bit of time in Amsterdam and thoroughly loved it and hope to return again soon! I am sure you will receive many applicants.
Do you have any photos of your cats that you can share on here? We would love to see. 
You mentioned you hope to also sit yourselves, whereabouts are you hoping to travel to? 
If you are members of TrustedHousesitters 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.
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. 
Another thread you may find helpful.
