I noticed my cat started peeing all over the place when he usually only used to pee in his litter. After some time I realized he was having hard time peeing and appearently paing too also I saw some blood in his pee. I was very worried so I took him to the vet and ver suggested me to stop giving him solid or even soft foods from brands. He suggested me to feed my cat with meat. For my cats case it was beef cause he loved that meat. Within a week i saw drastic changes I was so happy. And after about 3-4 months i started his normal solid diet and he is doing fine.
