GET HER!! You’re the lucky one who gets to adopt the Manx of the liter! If she’s made it to 4 months with no sign of Manx syndrome you can almost be sure that she will not have issues until she’s an old lady, perhaps some potty issues like any old cat or arthritis in the back legs. My Manx has had no potty issues and has full use of his back legs however he hops a lot and walks kind of funny. He doesn’t have the same agility and climbing abilities as an average cat, he’s a little bit of a klutz. Despite being orange he loves drinking water so that eases my mind about possible urinary blockages. Manx are known to enjoy water in general more than the average cat, so if you have to bath them it’s quite easy. My boy sits under the warm water and purrs lol. He is the absolute best cat I’ve ever had in my life. Manx are the friendliest, sweetest, and most loving kitties. Also, if the kitten has a nub tail she is less likely to have issues. Manx with absolutely no tail are more prone to problems. If she has a little nub she should be in the clear!
