I bought Pepsi some of the crunchy salmon treats which she doesn't like so I thought it was just that flavour and bought some crunchy catnip ones... she turned her nose up at them too! Like you said, she'll sniff it and then walk away, so now as a treat she gets a bit of tuna or chicken. She's getting the Whiskas stocking with the treats in a little tub, hopefully I'll have more luck with them otherwise I'll have tons of packets of treats around the house lol
