Two bonded kitties abt 4 years old (Portland)

I have these two girls that I unfortunately cannot keep due to my situation, moon is the striped kitty and Black is black; moon is very shy it takes her awhile to warm up to you, she likes quiet places, she loves to play and bug her sister. Black is more outgoing she’s a lot more vocal and sometimes super needy lol. They have been together since they were palm size, so I’m choosing to keep them together, for the sake of there hearts; I don’t want to stress them out too much during the already stressful move. They are not fixed.
