My name is Jack!

I am rehoming my cats Jack and Daisy. They have a big bond as they have been together since birth and came from the same litter. They are around 4 years old born in January or February 2020. I have had behavior issues with them since for the past 2 years and litter box issues with them for the past 3 years. I have done everything I can to help them deal with this issue. I have moved a lot with them in the past four years and I think they need a more stable environment. I had them in a shelter to be move up to adoption, but they were unable to keep them as they did not thrive there and said they would do better in a foster. Because they have issues peeing over the house, my landlord has instructed me to get rid of them or I risk loosing my house. They are both fixed and declawed. I am hoping with a new environment they will stop peeing outside of their litter boxes. They do use them and pee in them, but also pee outside as well.
