does anyone know anything about howling cats? mines 17, and the vet says she is just howling cos shes senile, she doesnt seem to be in pain cos when i go to her she purrs and seems happy enough but minutes later shes howling to herself again and its so distressing to hear, she also howls after she eats, in that she walks away from her food and then sits YOWLING until i go to her and pick her up. she also doesnt seem aware of her surroundings until i touch her then she chirps and comes back, then shes purring again. im going mad with worry here can anyione help???
