QuoteJustin Bieber is responding to PETA after the animal rights organization slammed the singer over his decision to buy two part-exotic kittens that cost a total of $35,000.

In a statement to PEOPLE on Thursday, PETA Senior Vice President Lisa Lange spoke out against Bieber's recent decision to purchase the expensive Savannah kittens, whom he named Sushi and Tuna, claiming that the singer does not "care" about helping animals.

Posting a screenshot of the PEOPLE story to his Instagram Story later on Thursday night, Bieber wrote, "PETA can suck it."

"PETA go focus on real problems," he continued in a second Instagram Story post. "Like poaching, and animal brutality. Ur tripping because I want a specific kind of cat? U weren't tripping when I got my dog Oscar and he wasn't a rescue."
