My cat has always been a licker. She will lick anyone that pets her or goes near her, even my other cat and dog. She used to have issues with her teeth and the vet ended up having to remove them all and this has given her no issues but I was wondering whether this could be related to her licking so much? There are times that she will lick me maniacally, like I am made out of cat food and won’t stop until I move. Do you think it is normal behavior?

My dog is scared of second hand shoes I bought after smelling them

I picked up 3 pairs of second hand shoes that I bought online from a seller. And as I opened the package my dog stuck her head in there smelling it and started smelling the shoes (specifically the one pair) as I took them out to try on. And then she ran outside with her tail between her legs and ears backwards. My other dog also smelled the shoes but she didn't react in fear, she reacted normally. I walked outside with the shoes on to fetch my dog but she wouldn't come near me with them on. So i took them off and went outside again to fetch her, and she was smelling the ground I walked on and was still cautious to come to me. However she realized I'm not wearing the shoes anymore and have started to calm down. It's just very strange, I've never seen her react like that to any 2nd hand items I've bought.

What smell could possibly make her so scared? And my other dog is unfazed.
