NEW YORK (TheStreet) -- Viewers had questions on many companies and Jim Cramer provided answers Tuesday from the floor of the New York Stock Exchange

On animal health company Zoetis  (ZTS), Cramer warned investors to be careful after what has been a very big run in the stock. He said Zoetis is a very good company but he thinks it's pricey at current levels.

Cramer said that with Whole Foods'  (WFM) new 360-store concept, the grocer has become a "show me" stock now. He explained there are many more companies in the organic food space, such as Target  (TGT), an Action Alerts PLUS holding, and Kroger  (KR). So investors will have to see if Whole Foods can prove itself.

Asked about cyber security company FireEye  (FEYE), Cramer said that despite the stock being up a lot, it's not that expensive compared with other companies in the sector. However, that doesn't mean the stock is cheap.

One viewer said Cramer has liked Kinder Morgan  (KMI) before and wondered if it is a buy right now. Cramer said short-sellers are all over this stock. However, he said CEO Rich Kinder is "terrific" and investors need to wait it out for a little while.

On Yelp  (YELP), Cramer said it is "all takeover" at this point. The company is worth a great deal and Yahoo!  (YHOO) should be buying it, although he doesn't believe that it will.

He called Ford  (F) a longer-term investment and said General Motors  (GM), another AAP holding, has been "enough of a House of Pain." Ford's numbers were "just okay," he said.

At the time of publication, Cramer's Action Alerts PLUS had a position in GM and TGT.
