Brooklyn bunny hoarder Dorota Trec on Wednesday called on an “expert” witness to bolster her $2 billion suit against the ASPCA over the confiscation her 150 allegedly mistreated animals.

Trec in Brooklyn Supreme Court presented contractor Mikail Nadler — who had occasionally seen the bunnies through a fence while working near her property — as an expert in “breeding, cleaning and washing” rabbits.

Under questioning, he said, “They play, they jump,” and he never saw them fight.

Trec, threatening to up her claim against the ASPCA to $6 billion, reportedly owes the ASPCA $50,000 for the care of the confiscated bunnies.
