I just recently started fostering 2 tiny kittens, about 5 weeks old...they are very energetic and my Manx has just acquired an attitude..The Manx is growling at my 3 dogs , my other big cat and me...she is growling, hissing and trying to bite me when I pick her up..Is this because of the kittens in the house? When I first got the Manx she was kind of like that and then she became very loving, now total 360..I did have the baby kittens in a wire cage , which I used for the Manx when I first got her...but I put the kittens in that cage and now I have changed the kittens to the bathroom with the door closed, I am afraid that the Manx will hurt them...Also I set the wire cage back up for the Manx, and put her in there tonight...I am worried about the Manx hurting one of my dogs, they are smaller than her...Now she is growling and hissing at me when I come into the room..I hope by putting her in this cage I have not upset her more....I really don't want to let the Manx out , unless I am with her....This was all of a sudden and very scarey....I thought she could be sick, but I feel it is the kittens....What do you think?
