It's a big cat birthday party this Saturday at the Franklin Park Zoo in Boston!

Want to help a pair of lion brothers celebrate their 9th birthday? The party is from 10 a.m. - 2 p.m. this Saturday at the Franklin Park Zoo.

Kids of all ages can enjoy the birthday festivities as African lions, Dinari and Kamaia, turn nine.

The party starts this Saturday at 10 a.m.(when the zoo opens) with a talk from Tina Ramme, a wildlife biologist and CEO of the Lion Conservation Fund. She'll speak about her work restoring lion populations and habitat in Kenya, plus they'll be an activity table for the kids.

There'll be lion-themed arts and crafts (like making lion masks), a giant birthday card for everyone to sign and even a lion birthday cake for the first 200 people there.

Though the lions won't be digging into the cake, they will be receiving special birthday enrichment treats to celebrate their big day.

All the lion birthday party activities are included with zoo admission, which is $19.95 per adults, $16.95 for seniors, $13.95 for kids 2-12 and free for children under 2.
