Are Roof Rats Legal in Poland? Keeping, Breeding & Selling

Roof Rat Laws › Poland

Summary. Poland is permissive for the roof rat. Rattus rattus is NOT on the EU invasive-species Union list (Reg. 1143/2014) and NOT on Poland’s national IAS list (Council of Ministers Regulation of 9 Dec 2022, Dz.U. 2022 poz. 2649), so the blanket keep/breed/sell/transport prohibitions in Art. 7 of the 2021 Alien Species Act (Ustawa o gatunkach obcych, Dz.U. 2021 poz. 1718) do not apply. It is also not on the CITES appendices (so no Starosta registration duty under the Nature Conservation Act) and not on the dangerous-animals list (so no RDOŚ permit). That leaves only the general Animal Welfare Act (Ustawa o ochronie zwierząt, Dz.U. 2023 poz. 1580) care duties (Art. 9). So a hobbyist may keep, breed, give away and transport captive-bred roof rats with no environmental or wildlife permit. Two real nuances: (1) COMMERCIAL breeding/dealing (organized, continuous, for profit) is a ‘supervised activity’ (działalność nadzorowana) requiring prior notification to the District Veterinary Officer (Powiatowy Lekarz Weterynarii) and a veterinary identification number (WNI) under the Animal Health Protection Act (Dz.U. 2023 poz. 1075), hobby give-away of occasional litters is not. (2) There is a genuine, unresolved statutory ambiguity about whether a captive-bred roof rat is a ‘domestic animal’ (zwierzę domowe) or a ‘wild animal’ under Art. 4 of the Animal Welfare Act; if ‘domestic,’ Art. 10a bars selling it at outdoor marketplaces/fairs (sales must occur at the breeder’s premises, the seller’s home, or a licensed pet shop). Local municipal sanitary rules require mandatory deratization of free-roaming rodents, so the practical duty is escape-proof indoor containment. Never release a roof rat.

Status by activity

Keeping / owning   Legal

Confidence: High · Last verified 2026-06-13

Keeping a captive-bred roof rat is legal with no wildlife or environmental permit. R. rattus is on neither the EU Union list (Reg. 1143/2014) nor Poland’s national IAS list (Rozp. RM 9 Dec 2022, Dz.U. 2022 poz. 2649), so the Art. 7 keeping prohibition of the 2021 Alien Species Act does not apply. It is not on CITES (so no 14-day Starosta registration under Art. 64 of the Nature Conservation Act) and not on the dangerous-animals list (so no RDOŚ permit). Only the general care duties of the Animal Welfare Act apply (Art. 9: shelter, daylight, free movement, food, constant water). Local municipal sanitary law (mandatory deratyzacja of free-roaming rodents) makes escape-proof indoor containment the practical obligation; an escaped roof rat is treated as a pest.

Breeding   Legal

Confidence: High · Last verified 2026-06-13

Hobby breeding of captive roof rats is legal with no state registration. The Animal Welfare Act’s breeder monopoly (Art. 10a) restricts commercial breeding to DOGS AND CATS only and explicitly omits rodents, so a private keeper raising a closed roof-rat lineage needs no breeding license or club affiliation. The Alien Species Act’s breeding prohibition (Art. 7) applies only to listed IAS, and R. rattus is unlisted. CAVEAT: organized, continuous, for-profit breeding/dealing is a ‘supervised activity’ (działalność nadzorowana) under the Animal Health Protection Act (Dz.U. 2023 poz. 1075), requiring prior notification to the District Veterinary Officer (PLW), a facility inspection, and a veterinary identification number (WNI); operating without it is an offence under Art. 85. Occasional hobby litters given away (sprzedaż okazjonalna) fall outside this commercial regime.

Selling or giving away   Legal

Confidence: Medium · Last verified 2026-06-13

Selling or giving away a captive-bred roof rat is legal. The Alien Species Act bans ‘introduction to trade’ (wprowadzanie do obrotu) only for listed IAS, and R. rattus is unlisted; no CITES certificate of legal origin is required. Commercial sellers are subject to ordinary consumer-warranty rules (rękojmia) and, if running an organized for-profit business, must hold the veterinary WNI (see BREED) and register in CEIDG. ONE GENUINE AMBIGUITY (why confidence is medium): Art. 10a of the Animal Welfare Act bans selling ‘domestic animals’ (zwierzęta domowe) at marketplaces, fairs and exchanges (targowiska, targi, giełdy). Whether a captive-bred roof rat is a ‘domestic animal’ (Art. 4 pt 17) or a ‘wild animal’ (Art. 4 pt 21) is statutorily unresolved (no Supreme Administrative Court ruling). Either way the animal may be sold/given away, but if treated as ‘domestic,’ that must be at the breeder’s premises, the seller’s home, or a licensed pet shop, NOT at an outdoor market. Practically, municipal sanitary rules would block a public-market sale of a synanthropic rodent regardless.

Transport & import   Legal

Confidence: High · Last verified 2026-06-13

Transport is legal. Domestic movement of a privately owned roof rat needs no certificate, passport or travel permit, only the welfare conditions of the Animal Welfare Act transport chapter (secure, ventilated, escape-proof container protecting against temperature extremes). Intra-EU NON-commercial movement (owner-accompanied, ≤5 animals, no transfer of ownership) is governed by EU Reg. 576/2013, under which pet rodents are ‘other species’ (Annex I Part B) exempt from the microchip/rabies/EU-pet-passport rules that bind dogs/cats/ferrets; Poland’s GIW advises carrying a basic vet attestation of good health for carrier policies. COMMERCIAL or >5-animal intra-EU movement uses an official intra-EU health certificate logged in TRACES NT (Comm. Impl. Reg. (EU) 2021/403); third-country imports must enter via a Border Control Post with a third-country health certificate. No IAS transport bar applies (R. rattus unlisted). Never release.

Restrictions & responsibilities

COMMERCIAL only: if you breed or deal in roof rats as an organized, continuous, for-profit business, it is a ‘supervised activity’ (działalność nadzorowana). Before starting, notify the District Veterinary Officer (Powiatowy Lekarz Weterynarii) at the local District Veterinary Inspectorate (PIW); the PLW inspects the premises (biosecurity, ventilation, waste, isolation of sick animals) and issues a decision entering you in the veterinary registry with a veterinary identification number (WNI). A for-profit business must also register in CEIDG (e.g. PKD 47.76.Z retail of pet animals / 46.23.Z wholesale of live animals). Operating without notification is an offence (Art. 85, punishable by fine/restriction of liberty). A hobbyist giving away occasional litters at cost is NOT a business and needs no WNI.
  • Hobby/occasional give-away: no registration required
  • Commercial: register the business in CEIDG with the appropriate PKD code
  • Commercial: notify the Powiatowy Lekarz Weterynarii (PLW) at the District Veterinary Inspectorate (PIW) BEFORE operating
  • Pass the PLW facility inspection and obtain the veterinary identification number (WNI)

Keeping a captive-bred roof rat is legal (not on the EU or national invasive list), subject to the Animal Welfare Act care duties (Art. 9). Two practical limits: (1) local municipal sanitary rules mandate deratization of free-roaming rodents, so the animal must be kept escape-proof indoors, an escaped roof rat is treated as a pest and the keeper is strictly liable (Civil Code Art. 431). (2) If a roof rat is treated as a ‘domestic animal’ under Art. 4, Art. 10a bars selling it at outdoor marketplaces/fairs (targowiska/targi/giełdy); sell instead at the breeder’s premises, the seller’s home, or a licensed pet shop. Never release a roof rat.
  • Keep escape-proof indoors (municipal deratization targets free-roaming rodents; keeper is strictly liable for escapes)
  • Do not sell at outdoor marketplaces/fairs if treating the rat as a ‘domestic animal’ (Art. 10a), sell at premises/home/licensed shop
  • Never release a roof rat into the environment
