Hong Kong, November 14, 2026 -- As urban pet-owning households face persistent infestations of fleas, ticks, flies, and pyrethroid-resistant bed bugs (Cimex lectularius), conventional chemical pesticides pose severe hepatotoxic risks to domestic cats due to their natural liver enzyme deficiency. Addressing this critical safety gap, Hong Kong biotechnology innovator GCC Pet BioTech (Green Concept Control) today announced the launch of the GCC Professional Dual-Action Pest-Control Tofu Cat Litter, the world’s first eco-friendly cat litter engineered to repel and eradicate household pests through a non-chemical, dual-layer biological defense system.

Dual Bio-Defense: "Repel" and "Infect & Spread"
Developed in Hong Kong, the 18L formula combines a 95% food-grade pea fiber and soybean pulp base—delivering rapid clumping and ultra-low dust—with two bioactive layers:
Layer 1 (Repel) — 4.5% Essential-Oil-Free Catnip Hydrosol: Steam-distilled Nepeta cataria hydrosol (containing zero concentrated essential oils) naturally repels flies, mosquitoes, fleas, and bed bugs by 81.5% to 92.4% in Y-tube olfactometer bioassays, while soothing feline stress without causing hyper-excitation.
Layer 2 (Infect & Spread) — 0.5% Patented G. Bassiana Fungal Spores: Dormant entomopathogenic fungal spores adhere to insect cuticles upon contact, secreting chitinase enzymes to penetrate exoskeletons. Laboratory bioassays confirm over 95% mortality within 7 days against fleas and resistant bed bugs. Contaminated pests also trigger a "Trojan Horse" horizontal transfer effect, eliminating 84% to 90% of unexposed nest-mates in crevices.
Thermodynamic Mammalian Safety
Unlike synthetic neurotoxins, the proprietary G. Bassiana strain ceases germination above 34°C, rendering it biologically incapable of infecting warm-blooded mammals such as cats (38.0°C–39.2°C) or humans (37.0°C).
"Pet parents should never have to choose between an insect-free home and their cat's health," said Dr. Gracia Chan, Lead Researcher at GCC Pet BioTech. "Proudly made in Hong Kong, our dual-action litter turns the everyday litter box into a continuous, non-toxic biological pest trap."
The GCC Professional Dual-Action Pest-Control Tofu Cat Litter (18L) is now available. For full laboratory reports and product inquiries, visit https://gcc.com.hk.
