Duck is a less common flavour in cat treats, and it is worth a try with a cat that has gone off the usual chicken and fish. This is the Dreamies duck flavour pack, 60 g of dry treats.
Trying a new flavour
Offer two or three pieces the first time and see how your cat takes to them. Some cats sniff a new treat and walk off, then come back for it an hour later, so leave one in the bowl before deciding it is a failure. Any new food can unsettle a stomach if a cat eats a lot of it at once, so start small.
The pack lists a suggested daily amount and any age guidance. Keep treats to a small share of the day's food and leave fresh water out as usual.
Good to know
Clip or fold the pack shut after opening, and store it somewhere dry.
If duck does not win your cat over, there are plenty of other flavours under more Dreamies treats and other brands in dry cat treats. Ordering and payment questions are covered in the FAQ.
