As do a few posts in this thread, including the one right above yours.
So, what point is it, exactly, that you are trying to make? If it is that my post is repetitious, so be it but, apparently, so are are others since you use the phrase, “a few”.
I know what point he is trying to make! 
And no, I am not telling you either!
We do encourage posters to read the thread before chiming in with something that has already been said multiple times, yes.
Yes, your point was repetitious, as was a poster several posts earlier. Hence, ‘a few’. Which I also called out for repetition. (Which is one of my pet peeves.)
Look, I’m not trying to be snarky, but, seriously, the post immediately above yours referenced Ralphie the buffalo.
Since I have a nagging feeling that CU-Boulder’s Ralphie the Buffalo may have already been covered … an hour away, in my town, lurks this guy:
Oh Black Betty, Cam the Ram a-lam…
The University of Tennessee Volunteers have had a series of big ol’ floppy hounds, all named Smokey. The Rochester Red Wings, the Washington Nationals’ AAA affiliate, have Bruce the Bat Dog.
My high school team is the Amherst (Ohio) Comets. We adopted Halley’s comet but didn’t realize it only appeared every 76 years. And even then we couldn’t see it. Sucks not having an astronomy department.
the NFL’s Atlanta Falcons used to have a living falcon as a mascot, back when they played in an open air stadium. You can probably see where I am going with this. One day the falcon flew off and was eventually found in a parking lot.
I thought I read that they had reinstated the live falcon now that they play in a dome, but couldn’t find confirmation online,
U. of Washington, not Washington State
However, Washington State, where the sports teams are nicknamed the “Cougars,” did use live cougars as mascots from 1927 until 1978 – all of them were named “Butch,” after a WSU quarterback from the 1920s, Butch Meeker. The school has used a person in a cougar costume since then.

Columbia University, home of the Lions, brought out a live lion at the 1934 Rose Bowl and again at a 1963 game against the Princeton Tigers. The school also had occasional visits from Matilda, the Harlem Goat in the 1910s.
Dang, not only did I know that, the name Dubs is a clear giveaway.
My alma mater, the University of Florida, does not have a live alligator mascot, but there are live gators on campus (particularly in Lake Alice).
From Princetoniana:
In 1923, a live tiger who had been captured in India by the father of a football player, Albert F. Howard '25, was brought to Princeton as a mascot; but after several weeks of mounting community anxiety he was given to a zoo.
@Railer13 Sorry, my bad. Missed it but shoulda known and at least searched the thread for “Ralphie”
Siena College (now Siena University) added a Saint Bernard dog named Baloo as a mascot in 2022.
I do wonder if Alabama keeps a bucket of red algae as mascot…
Or a nuclear submarine. 
Despite being officially called the Crimson Tide, their mascot is an elephant, for reasons.
