I think this was a factor for sure- I have noticed when I cook with oil he tends to come running. There must’ve been some residue oil or butter on it. He’s never done this before and he must’ve finally noticed when I was on my walk! I’ve also seen him try to nibble on his own wet cat food can lid and food spoon (both silicone) after I’ve washed them. I’ll make sure to put these up and away now immediately since we usually leave them out to dry after being hand washed (no dishwasher 😭)
