Roof Rat Laws › Switzerland
Summary. Switzerland is legal for the roof rat, confirmed in writing by the federal veterinary office (BLV) on 15 June 2026. Keeping and breeding house rats (Rattus rattus) are permitted, and keeping small rodents needs no permit and no proof of competence (Art. 89 let. a of the Animal Welfare Ordinance, TSchV). The same welfare rules as for the fancy rat (Rattus norvegicus) apply: rats are social, so at least two must be kept, and the enclosure must meet the Annex 2 minimum dimensions (the BLV points to the German Säugetiergutachten 2014, about 2 square metres for two house rats). A cantonal permit plus recognised training is required only to breed and give away more than 300 rats per year to third parties (Art. 94 para. 2, Art. 101 let. c para. 4 TSchV), so an ordinary private keeper or hobby breeder needs nothing. R. rattus is on no CITES appendix and no Swiss invasive-species list. Import and transport depend on the country of origin (EU or non-EU) and whether the owner travels with the animals, so check the BLV travel guidance. Never release a roof rat.
legal note
This is a research aid, not legal advice; rules change and are interpreted by local officials. Verify with the official source before acting.- The BLV (Swiss Federal Food Safety and Veterinary Office), through its Customer Communication desk, confirmed in writing on 15 June 2026 that keeping and breeding house rats (Rattus rattus) are permitted in Switzerland.
- Keeping small rodents needs no permit (Art. 89 let. a of the Animal Welfare Ordinance, TSchV). A cantonal permit is required only to breed and give away more than 300 rats per year to third parties (Art. 94 para. 2 and Art. 101 let. c para. 4 TSchV).
- Husbandry follows the minimum requirements in Annex 2 of the TSchV. Because the Ordinance sets no species-specific minimums for Rattus rattus, the BLV advises meeting at least the same requirements as for the fancy rat (Rattus norvegicus), including keeping them in pairs or groups, and points to the German Säugetiergutachten 2014 (about 2 square metres for two house rats) as a guide.
- Import and transport requirements depend on the country of origin (EU or non-EU) and whether the owner travels with the animals; the BLV refers to its ‘travelling with pets’ page for the conditions.
Status by activity
Keeping / owning Legal
Confidence: High · Last verified 2026-06-15
The BLV confirmed in writing (2026-06-15) that keeping house rats (Rattus rattus) is permitted in Switzerland and that keeping small rodents needs no permit (Art. 89 let. a TSchV). Mandatory welfare conditions apply: rats are social, so keep at least two (TSchV Art. 13 and Annex 2), and meet the Annex 2 minimum husbandry requirements, at least the same as for the fancy rat R. norvegicus (the BLV points to the German Säugetiergutachten 2014, about 2 square metres for two house rats). No cantonal permit and no proof of competence are needed for private keeping.

Breeding Legal
Confidence: High · Last verified 2026-06-15
Private breeding for personal use or occasional rehoming is permit-free. A cantonal Bewilligung + recognised training (Sachkundenachweis/FBA) is required only above the commercial threshold, 300 rats given away (or used as feeder animals) per year, or for any ‘gewerbsmässiger’ (commercial) pet dealing. A normal hobby rattery stays well under 300/yr. (Same Wildtier-classification caveat as keeping.)

Selling or giving away Legal
Confidence: High · Last verified 2026-06-15
Gratuitous transfer (giving away) of captive-bred rats with no commercial element is lawful without a permit below 300 animals/year. Commercial trade (‘gewerbsmässiger Handel’) at any scale needs a cantonal Bewilligung + BLV-recognised training; organised animal swaps (Tierbörsen) have their own permit/training rule. No price cap; the test is whether the activity is commercial.

Transport & import Legal
Confidence: Medium · Last verified 2026-06-15
Internal transport needs only welfare-compliant conditions (TSchG Art. 3). Non-commercial personal import of up to 5 healthy rodents from a non-EU country needs no import permit and no health certificate (BLV travel rules; checks possible at Zürich/Geneva). Commercial import (resale/breeding stock) needs a BLV import authorization + possibly an origin health certificate. R. rattus is not on any CITES appendix, so no CITES permit. Never release.
