Our 4 month old kittens were spayed last week . Unfortunately one of their scars has not healed so she has been given a body suit to wear . Her sister has gone crazy - hissing and growling , won’t go near her . Very upsetting as they were so affectionate before and were rarely apart. I’ve had to separate them now for bed time and can just hear them howling . Anything we can do to make kitten 1 remember who her sister is and not be so distressed ?
