Hello @ghill16 and welcome to the forum. First, let me say those are two real cuties you have there and I know it breaks your heart to try and understand what they may have previously gone through before they found their forever home with you. Animals, like people, are scarred from past history and it can be very difficult to know exactly what they need to help them past their fears and anxieties. There are many helpful posts here regarding anxiety and stress with our furbabies and this one Signs of Separation Anxiety, Stress - All About Pets - TrustedHousesitters Community Forum talks about separation anxiety and stress.
I see you have not joined TrustedHousesitters yet and once you do, you will be able to reach out to so many experienced sitters who know how to and are willing to care for your special ones. You will just need to sign up and set up your profile with more great pics of your home and those two cuties. Please just make sure you include all this information in your profile so there is no confusion or doubt with a potential sitter.
Looking forwarding to seeing your dates posted soon!
