IT'S CALLED "CATALYST"
OH NO WAIT IT'S A SERIES oh god
Barque cats - for those who didn't spend middle-school reading horrible science fiction novels about the love lives of space psychics - are large, intelligent telepathic cats who enjoy being in zero gravity and can warn you when there's a problem with your spaceship. I totally wanted one when I was twelve, though I unfortunately didn't have any zero gravity to keep it in.
This sentence is in the synopsis:
When corrupt government officials declare a plague and plan to destroy animals across the galaxy, including the Barque Cats, two young people (a veterinarian and a cat person), a clever Barque kitten and the boy who is its special person, an ancient Egyptian cat with mysterious powers and a hidden agenda, and a con man join forces to try to prevent the tragedy.
You know, I don't think that's a sufficiently rag-tag band of rebels. We still need, like, a disillusioned ex-cop with a drinking problem, a quick-witted halfling thief, a robot who wants to learn to love, and the Doctor. Get with the program, McCaffrey.
Actually, sorry - Elizabeth Ann Scarborough's name's on there as co-writer. Given McCaffrey's recent health problems, Scarborough may be the actual author of this excellent work. Especially considering the whole "an ancient Egyptian cat with mysterious powers and a hidden agenda" business. That is a very Scarborough kind of idea. Also, this is the sequel (which is called Catacombs):
The barque cats, mistaken for a public health hazard, flee Earth for the feline-dominated planet, Mau, with the help of Pshaw-Ra, a mysterious cat with his own spaceship. Oddly, no one--including the humans--is bothered that he plans to take over the universe on behalf of felinekind.
Yeah, I see the invisible hand of the Scarborough in that storyline. It sounds like it might actually attempt humor, a property which McCaffrey has always scorned.
...I admit at this point that I'm kind of thinking about reading these.
