Please tell me more about the bubble backpack, I have a cat that might like traveling with me.
she doesn't like to ride in cars, and is wary of elevators, but loves going to the pub. she's happy to sit in it with the backpack open when she's not at home, and simply purrs and rubs her face/head on my hands when i reach in to pet her.
one warning: it is an attraction, she has had many people wishing to take photos of her ... thankfully she loves getting her picture taken.
editing to add: this is the one i purchased - https://www.amazon.com/gp/product/B01J2V5LOM
i can provide a photo of her in it if really needed
I've seen someone wearing something like this one once https://www.chewy.com/pet-gear-i-go-plus-traveler-black/dp/4... seems like a better idea.
she is never in high heat while in her backpack, and airflow is very good throughout it.
