Inspector Quadro K

0.4 ml, spot-on solution for cats 1-4 kg
Assessed clinical scopeCat · Labelled feline topical scope for the exact weight band: ectoparasites, gastrointestinal nematodes and cestodes, and heartworm-larval prevention · On the skin
Care settingVeterinary-selected home application to dry intact skin after parasite and heartworm assessment, with diagnosis-specific follow-up
vetman score 6.0/10 Situational / acceptable
Evidence confidence: Low Georgia: Yes, veterinary · № 000155 · Verified on 21 Oct 2026

Registered exact feline spot-on with manufacturer instructions and small exact-product studies, but the Bulgarian register links the wrong product SPC. Use only in cats within the exact weight band, with explicit parasite selection and follow-up.

Regulatory and scientific credibility5.5/10

Exact strengths have current Georgian registrations and an indefinite Bulgarian register entry. Confidence is reduced because the Quadro K page links to the Quadro C dog SPC rather than a K-specific feline SPC; the exact K instruction is available from the manufacturer.

Clinical efficacy6.0/10

An exact-product report found high activity against several natural infestations, but groups were small, control detail limited and an author was affiliated with the producer. The broad label has moderate, not definitive, clinical support.

Safety and tolerability6.0/10

A small exact-product study found no measured abnormalities at up to five times the label dose, but cannot exclude uncommon harms. Licking, overdose, reproduction, age or illness, other antiparasitics, ear integrity and environmental exposure need safeguards.

Clinical practicality7.0/10

A whole weight-banded pipette simplifies routine dosing. Direct-to-skin placement, prevention of licking, keeping dry and separation until dry add practical burden.

Full-course cost-effectiveness-

Price was not assessed and is excluded from the overall score.

Important safety and use flags

  • Do not use with hypersensitivity, infectious disease or debilitation, on wet or damaged skin, or outside the exact labelled species, age and weight band.
  • Do not combine with another antiparasitic unless a veterinarian has checked ingredients, intervals and cumulative toxicity.
  • During pregnancy or lactation and below 1 kg, use only after an individual veterinary benefit-risk assessment.
  • For ear-directed use, confirm tympanic-membrane integrity; with a perforated eardrum the product must not enter the ear canal.
  • Prevent licking and monitor for local irritation, depression, hypersalivation, tremor or vomiting; wash off and assess after overdose.
  • Keep treated animals away from rabbits, bees, fish and surface water; prevent environmental transfer until dry.
  • Heartworm use prevents susceptible larval stages; it is not adulticide treatment. Assess infection and exposure first.
