“You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.”

— Albert Einstein

Earliest published version found on Google Books with this phrasing is in the 1993 book The Internet Companion: A Beginner's Guide to Global Networking by Tracy L. LaQuey and Jeanne C. Ryer, p. 25 http://books.google.com/books?id=sP5SAAAAMAAJ&q=meowing#search_anchor. However, the quote seems to have been circulating on the internet earlier than this, appearing for example in this post from 1987 http://groups.google.com/group/comp.lang.c/msg/cc89abb5e065d23f?hl=en and this one from 1985 http://groups.google.com/group/net.sources.games/browse_thread/thread/846af15b5a38c35/3d6d5a639c24bba3. No reference has been found that cites a source in Einstein's original writings, and the quote appears to be a variation of an old joke that dates at least as far back as 1866, as discussed in this entry from the "Quote Investigator" blog http://quoteinvestigator.com/2012/02/24/telegraph-cat/#more-3387. A variant was told by Thomas Edison, appearing in The Diary and Sundry Observations of Thomas Alva Edison (1948), p. 216 http://books.google.com/books?id=NXtEAAAAIAAJ&q=edinburgh#search_anchor: "When I was a little boy, persistently trying to find out how the telegraph worked and why, the best explanation I ever got was from an old Scotch line repairer who said that if you had a dog like a dachshund long enough to reach from Edinburgh to London, if you pulled his tail in Edinburgh he would bark in London. I could understand that. But it was hard to get at what it was that went through the dog or over the wire." A variant of Edison's comment can be found in the 1910 book Edison, His Life and Inventions, Volume 1 by Frank Lewis Dyer and Thomas Commerford Martin, p. 53 http://books.google.com/books?id=qN83AAAAMAAJ&pg=PA53#v=onepage&q&f=false.
The wireless telegraph is not difficult to understand. The ordinary telegraph is like a very long cat. You pull the tail in New York, and it meows in Los Angles. The wireless is the same, only without the cat.
Variant, earliest known published version is How to Think Like Einstein by Scott Thorpe (2000), p. 61 http://books.google.com/books?id=9yrYQxBgIYEC&lpg=PP1&pg=PA61#v=onepage&q&f=false. Appeared on the internet before that, as in this archived page from 12 October 1999 http://web.archive.org/web/19991012152820/http://stripe.colorado.edu/%7Ejudy/einstein/advice.html

“The problem comes up because we ask the question in the wrong way. We supposed that solids were one thing and space quite another, or just nothing whatever. Then it appeared that space was no mere nothing, because solids couldn't do without it. But the mistake in the beginning was to think of solids and space as two different things, instead of as two aspects of the same thing. The point is that they are different but inseparable, like the front end and the rear end of a cat. Cut them apart, and the cat dies. Take away the crest of the wave, and there is no trough.
Here is someone who has never seen a cat. He is looking through a narrow slit in a fence, and, on the other side, a cat walks by. He sees first the head, then the less distinctly shaped furry trunk, and then the tail. Extraordinary! The cat turns round and walks back, and again he sees the head, and a little later the tail. This sequence begins to look like something regular and reliable. Yet again, the cat turns round, and he witnesses the same regular sequence: first the head, and later the tail. Thereupon he reasons that the event head is the invariable and necessary cause of the event tail, which is the head's effect. This absurd and confusing gobbledygook comes from his failure to see that head and tail go together: they are all one cat.
The cat wasn't born as a head which, sometime later, caused a tail; it was born all of a piece, a head-tailed cat. Our observer's trouble was that he was watching it through a narrow slit, and couldn't see the whole cat at once.”

“When its 100 degrees in New York, it's 72 in Los Angeles. When its 30 degrees in New York, in Los Angeles it's still 72. However, there are 6 million interesting people in New York, and only 72 in Los Angeles.”

“She set you down on the floor and you started ranging around, picking things up, pulling my cats tail- you screamed like a banshee when the cat scratched you, so I asked your mother if youpart banshee. She didn't laugh."

“You turned into a cat! A SMALL cat! You violated Conservation of Energy! That's not just an arbitrary rule, it's implied by the form of the quantum Hamiltonian! Rejecting it destroys unitarity and then you get FTL signalling! And cats are COMPLICATED! A human mind can't just visualise a whole cat's anatomy and, and all the cat biochemistry, and what about the neurology? How can you go on thinking using a cat-sized brain?”
