Kane scored in the 14th, 32nd and 37th minutes as Spurs made it eight straight league wins at White Hart Lane.
Dele Alli scored in first-half stoppage time to complete the rout against mid-table Stoke.
Pochettino added: "He's one of the top strikers in the world and I think he deserves it because he's a great professional and top man. I'm happy for him.
"It doesn't surprise me, because I've told you many times that for me he's one of the best strikers in the world.
"This season we are not only winning games [at White Hart Lane], we are playing very well here - maybe because we all know it's the last season here and it's a very special atmosphere on the pitch and in the stadium."
Analysis by former Tottenham midfielder Jermaine Jenas on Radio 5 live
That was a special performance by Harry Kane. There are only a select number of players who can score like he can on their weaker side.
More often than not, if he is in the box, he will hit it. It goes through bodies, goes through legs and ends up in the back of the net.
I just don't know how much more of a warning you need when he is on the edge of the box with the ball. He is lethal with both feet. You need to close him down. When you're hot, you're hot. It's as simple as that.
Former England striker Alan Shearer, who scored a record 260 Premier League goals: "Calm down Harry Kane! What is he after...a Premier League record or something?"
Former Tottenham striker Gary Lineker tweeted: "A third hat-trick for Kane in nine games. The last person to do that was....someone else."

Problem: Article: Junior Hoilett opened the scoring by unleashing an unstoppable effort from the edge of the box.
QPR's lead was doubled when Tjaronn Chery's perfectly-weighted ball found Sebastian Polter, who slotted underneath David Button.
Chery secured the three points shortly after with a composed finish, his fourth goal in four Loftus Road games.
The Rs remain in 11th despite their west London derby win, while the Bees stay 17th.
Brentford's best chance came straight after Hoilett's opener, but Ryan Woods' fierce strike from long range struck the base of the post.
Former centre-back Dean Smith will be concerned with his Brentford side's defence, which has now conceded 12 in the last four away games.
The result sees QPR win three home games in a row for the first time since 2014.

QPR boss Jimmy Floyd Hasselbaink: "We were very well organised, not really in trouble, and we defended well. I'm very happy with the performance.
"Junior took the goal really well and then after that you get a little more positivity and you can do certain things - you feel freer.
"You can't just control a game with the ball, you have to be able to suffer without the ball as well, and we did that."

Brentford manager Dean Smith: "I thought the game turned on the second goal. There should have been a free-kick and they scored.
"We lost confidence after that. With the results we've been having, confidence is low.
"Goals change games and the second goal changed it. We always believed we were in it."

Problem: Article: Roy Wooldridge, 97, of Hendy, Carmarthenshire, was captured in France while on a secret mission just before D-Day in 1944.
He was taken to Erwin Rommel who decided he should not be shot.
Mr Wooldridge, who was twice awarded the Military Cross, later lived in Cardiff, where his funeral was held.
The Royal Engineer previously recounted his memories of war on the BBC's Antiques Roadshow in 2014.
He recalled how Rommel asked if he needed anything and he replied "a pint of beer, cigarettes and a good meal".
His collection of war memorabilia, including the empty cigarette packet given to him by Rommel, was valued at Â£10,000 by experts but he did not want to sell it and it will now be donated to the Imperial War Museum in London.
Mr Wooldridge went to Llanelli Grammar School and graduated from Aberystwyth University with a first class honours degree in mathematics.
He married three days before a telegram ordered him to report to his unit and he was sent to the French beaches to ensure there were no mines which could blow up the boats during the D-Day landings.
After the war, he lectured at colleges in Brighton, Wolverhampton and Lanchester in Coventry before becoming college principal in Derby.
Mr Wooldridge did not talk about his experiences of war until much later on in his life.
"He had a good war, not that we heard much about it when we were growing up," his son Ian Wooldridge said.
"He didn't talk about it a great deal, many of the people who came back didn't, but certainly he was regarded as a hero. The Military Cross and bar bear testimony to that."
"He always regarded Rommel as a man of honour who fought a clean war, despite the fact Hitler had ordered anybody captured without names tags, which our father was, was to be shot," he added.
"Rommel didn't agree with that and so dad always reckoned that it was Rommel who saved his life."
Mr Wooldridge died on 9 December. A procession with a New Orleans-style jazz band was held on Thursday ahead of his funeral at St Martin's Church in Roath.
