Salt and Pepper are adorable and after a day or so of glaring at each other, now are absolutely fine in each other's company. Having Pepper however, has made us realize how very under-developed Salt is, not just in size but in her behavior too. She is basically very quiet. When the vet examined both kittens last week, she did express concern about Salt and voiced the notion that her 'poorer' start in life may have long term effects. She had a huge worm burden when we first got her which we sorted but today Salt has been quieter than usual and also less hungry so we are a little bit concerned.
