(CNN) - It's sad when any relationship breaks up, but how about one between two tortoises that have been together for over a century, and suddenly they can't stand each other.
You would need a neck rub if your 115-year-old marriage just broke up. No more happy anniversaries.
For Bibi and Poldi, these two giant tortoises at a zoo in Austria, are both said to be 115-years-old and they were brought up together.
But it was love on the rocks after Bibi, the female, took a chunk out of her mate's shell.
"They just go at each other. At first, it was only the female who attacked the male and bit him. But now you get the feeling they can't stand the sight of each other," said Zoo Director Helga Happ.
They don't even want to be in the same enclosure.
Zookeepers don't understand what went wrong after 115 years of togetherness, but people posting online have plenty of theories.
"Every time she wanted to talk about the relationship, he retreated into his shell," said one poster.
"My guess is she caught him making eyes at the 90-year-old bimbo in the enclosure next door," said another.
Talk about irreconcilable differences.
"There's always a danger that they will bite each other so hard that one of them will bleed to death," said Happ.
On the bright side, 115 years sure beats Kim Kardashian's 72 days of matrimony.
We haven't been this distraught about a breakup since Pedro and Buddy, the so-called gay penguins at the Toronto Zoo, who were separated by keepers and put into a breeding program.
Bibi and Poldi are taking marriage counseling of sorts. Zookeepers are trying to inject a little fun back into the relationship by getting them to play games together.
Imagine at 115, single again, and looking for a hot tomato.
