Hello.
I'm not used to dry catfood.
The vet recommended Hills dental dry food. I just give cat boy some pieces every day to help his teeth so it's not being used up very quickly. It's a 1.5kg bag with a re-sealable top and I've had it for about two months.
The pieces of food now feel a bit sticky or tacky. Does that mean it's gone off? How long should it last?
I don't want lovely cat to be ill.
TIA
