From what I've researched so far it seems the Sphynx is a more "mobile" cat that does not mind being in the car and accompanying you on day trips. If this is true, I was wondering what you bring along for travel- especially for when your kitty needs to "relieve" him/herself. For example, I would love to bring my sphynx when I go to visit my parents for the day. My concern is, would I need to bring a litter box or is there an alternative? Anything else that I should consider for day travel? Thanks!
