Every morning our cat waits at the door to be let in for breakfast, but yesterday he was not there, we were worried, after lunchtime he returned but looked weary, spent he day not eating and drinking very little, we kept him in but today no change, we are taking him to the vets tomorrow as its the only appointment with pet aid, im so worried bout him, has anyone seen similar, he is a 6yr old male normally very healthy, im hoping its not bad, kids love him to bits.
