6 year old female littermate cats (Sherman)

2 females. Birthday is in August of 2019. Rehoming due to increasingly worsening health issues. They are very good cats. One is a tortie for sure and the other could be seen as calico or tortie, honestly. I can text pictures. They will come with litterbox, and whatever food and litter they have left. Free to good home. They are both spayed but not up to date on shots. We keep frontline on them. They do go in and outside but are mainly indoor cats and they stay in our yard. We joke that they are more like dogs. We have had them since they were kittens.
