We're going to make a tepid suggestion, and please bear with us, but maybe travelers can go to an actual zoo and look at actual baby lions, that are actually physically present.
There are all kinds of AZA-accredited zoos all over the country with lion cubs who just went on exhibit. Both the Maryland Zoo in Baltimore and the Reid Park Zoo in Tucson have infants around their exhibits, and we've embedded videos below to entice you to go forth and visit them. Meanwhile the Oregon Zoo is in the process of baby-proofing its space in anticipation of letting its own litter into the sunshine on a regular basis (zookeepers have to among other things drain the moat, because babies are stupid). Video of what that looks like is also embedded below.
And yes of course we keep track of these things with Google Alerts. Doesn't everybody?
