Forest experts say the tigress' popularity is akin to India's most famous feline 'Machli', of Rajasthan, who died last week.
"Royal Bengal Tigress T-15, popularly known as 'Collar Wali' (one with a collar), has given birth to 22 cubs in six separate litters since 2008. I have not heard of any tigress that has given birth to 22 cubs anywhere," Pench Tiger Reserve's field director Subharanjan Sen told Press Trust of India.
The tigress gave birth to five cubs in 2011 and reared all of them, he said.
According to the last tiger count of 2014, the striped animal population in PTR, spread over Seoni and Chhindwara districts of MP, was between 35 and 49, he said.
T-15 is known as 'Collar Wali' as she was the first tigress to be radio collared in PTR for tracking her movements, though her radio collar is defunct now, another forest official said.
'Collar Wali' gave birth to 22 cubs in 6 litters between 2008 and 2015, said Kanha Tiger Reserve's field director Sanjay Shukla, who is former Chief Conservator of Forests, Seoni that houses PTR.
Mr Shukla said the Department of Post issued a special cover envelope of Collar Wali on World Sparrow Day last year (March 20, 2015). Besides, New Zealand and Canada too issued personalised stamps on the tigress last year.
The tigress was born to tiger T-1, also known as Charger, and tigress Badimata in 2005, wildlife activist from Seoni, Sanjay Tiwari said.
Charger and Badimata too used to be a major tourist attraction once, he informed.
Mr Tiwari said "tiger enthusiasts both from India and abroad are crazy about Collar Wali. They stay put in hotels just to get a glimpse of the tigress".
Earlier, India's most famous tigress 'Machli', of Ranthambore Tiger Reserve, died last week. The tigress was born in 1996 and was considered the world's oldest big cat. The feline had 11 cubs.
