"Vampire Cubs' Pets"

[These tigers can change their skin color freely, and they usually feed on other beasts or monsters' blood.] 

As for why they're called love vampire tigers...

[The scary thing is, when their skin color changes to black and pink, they can activate a completely new ability.] 

[This ability allows them to bite their targets and turn their victims into the same kind as them.] 

[Some victims will also become zombies who are obsessed with these tigers, as if in love. This is why the tigers are called love vampire tigers!] 

[A few more interesting facts. These tigers are rumored to be the blood clan's pets for the younger generations. It was said that whenever there are blood clan cubs, the tigers will gather.] 

No one could affirm whether this fact was true or not because the monsters and beasts at the Death Meadow were really unique.
