mushy poop? Options

[JezebelandI]

hi everyone!
i own a blue abyssinian who is 4 this year, recenly her poop has been mushy, but not completely liquid, like diarrhea.
she currently eats whiskas dry food, and has a 2 chicken wings a week (shes been eating it since she was a kitten) she used to have hills science diet and royal canin before i bought her from the breeder which was a few weeks ago (she used to be a breeding cat) she's still very healthy and active and has a good appetite. she also gets a bit of cheeese once in a while.

she's an all indoor cat and i give her some grass every few days.

she has been vet checked before she came to me and there are no worms in her poop.
thank you！

Diet change often causes soft stools, you're better off keeping her diet the same as the breeders for several weeks and slowly changing over foods over a period of a few weeks mixing the new food in with old.

would watch the cheese, as cats can't really digest that, and the Whiskas would be making her poop runny. It is not described as the maccas of cat food for nothing
