I have just found a stray kitten who has diarrhoea. He (I think) appears to be about 6 weeks old, very lively and affectionate but with thin liquid diarrhoea, yellowy-brown with very little odour. The anus is red. One eye seems to be slightly more closed (the left). He is very thirsty and hungry, quite thin but not at all droopy. He also miaows a lot when I appear and definately wants company. He is also very interested in his surroundings and wants to explore. Not scared of the dog. Any suggestions? I am leaning toward Phosphorus or Sulphur.
