Recently, my youngest cat, Millie, had to be put down due to a blood clot blocking flow to the hind legs. I have two other cats (and one dog) that make up my animal family, but one catâ€”Joelâ€”was particularly attached to Millie; they grew up together, went into heat for the first time together, would groom each other, cuddle with one another, play together.. and on and on. Now, Joel seems to be handling the grief well, but definitely exhibits signs of grieving, like being overly affectionate, talking more than usual, sleeping/lounging in unusually spots, and overeating. Our eldest cat, Sabby (also Joelâ€™s mom), will play with Joel sometimes, but she doesnâ€™t seem to be getting the interaction she needs from her feline family. How can I help her cope with the loss of her sister? When will it be right to get another kitten, if ever?
