Selene was reunited with her little sister on Sunday. Our blondie, which we named Yuki, was crying at night and was very scared because she was alone. The two kitties are very different. Selene is more tranquil and she prefers to spend her time under the bed. Yuki must explore everything around to see what she can find, she’s very curious. And, as they are taking each other’s example, Selene started to follow her sister in the room, and Yuki started to sleep under the bed, even if she would rather sleep somewhere else, maybe in the bed. 
Because she knows me longer, Selene starts purring when I take her in my arms and caress her (after I got her out from under the bed). Yuki doesn’t feel as close to me, but she is willing to accept my caresses, of course after I get her out from under the bed, too.
Happily the reunion of the two little sisters meant good things for both of them. Selene is now more courageous and she explores the room in a more relaxed manner, and Yuki stopped crying at night. They would be very happy to be adopted together, we would be even happier for them, too. At the moment they are still fearful, but I think in a few days they will adapt more and more. If they will be taken apart, a regression is possible to happen, and they would miss each other a lot. 
And, to reunite the family even more, we’ve gone tonight to their initial location with the hope of catching the other two kittens and taking the mother cat to be neutered. Unfortunately the little kittens had disappeared and the neighbors in the area haven’t seen them today (but saw them yesterday). If they don’t show up tomorrow, it’s likely they were taken by someone, and we hope they found loving homes. We’ll be back there soon to catch the mother cat in order to take her to the vet to be neutered.
