Following the death of Sir Patrick Moore, Sussex charity Cats Protection said: “We were deeply saddened to hear of the death of Sir Patrick.
"A dedicated and lifelong cat lover, Sir Patrick supported Cats Protection in many ways over the years, from donating funds through his book sales to hosting fundraising garden parties at his home in West Sussex on behalf of his local Cats Protection branch.
"He was a special man who had cats at his heart and will be sorely missed by us all.”
Sir Patrick Moore hosted an episode of Sky at Night in September where he reflected on the lives on Neil Armstrong and Bernard Lovell.
Moore, British television's longest serving presenter, hosted the monthly documentary since its first airing on 24 April 1957 until his death today.
In 1970 Patrick Moore interviewed astronaut Neil Armstrong about his Moon visit on the BBC's Sky At Night.
He asked the Apollo 11 mission commander about what it was like on the Moon and if he could foresee scientific bases there.
Dr Brian May had been visiting Sir Patrick Moore during his recent illness and yesterday appealing for messages from his Twitter follows to take to the ailing astronomer.

I took your kind messages down to him yesterday afternoon, tweet folks. Not sure how much he took in, but he felt the love. THANKS. Bri
Patrick was very peaceful in his last hours. With his beloved cat Ptolemy purring on his bed. And his pals all around. A great innings.
