Sometimes Poppy will get bored of her food, so what I do is change how I give it to her every day to make it interesting.
She eats wet food in pouches which come in different flavours, I also have different flavoured kibble for her.
Some days I will add kibble to her wet food and other days I dont, some days I will put cheese or gravy on her dinner and some days I dont.
I always use the same brand of food for her but in different flavours.
I remember when I was little I was a really fussy eater, when my mum found something I would actually eat she used to give it to me ALL the time.
In the end I ate it so much I didnt like it anymore.. so thats why I try and give Poppy a bit of variety.
