Fingers crossed

For a while now I havent been happy with tilly and sprouts eating habits.
Sprout has always been a grazer and tilly was turning out to be the same. But a couple of months ago I was concerned that tilly wasnt putting enough weight on and sprouts tummy was almost whistling and what was coming out of his back end wasnt very nice at all..
We took sprout to the vets and they gave him an injection and pills. He was better for a while but then started again. We took tilly but they said she was ok for her age. We decided to wean them onto a different food. They have always had dry food and we tried some more for sensitive tummies. No better still not eating properly and poorly tummies. Until that is I decided to soak the food in boiled water. Hurray! For two days now they stand and eat until the bowls are empty and we have mmm shall I say solid ones too hehe.
