A Deutsche Bahn maintenance worker at Minden station reported two cats on the morning of 4 May. Neither animal was wearing Deutsche Bahn livery. Neither was registered in any national database. Deutsche Bahn confirmed the cats were not Deutsche Bahn property. Deutsche Bahn does not keep cats.
This was established quickly. Establishing what the cats were doing at Minden station has taken longer.
Minden station was the subject of a related incident in 2025, previously reported. A camera carrying a Deutsche Bahn logo had been pointed at Bundeswehr transport movements. Investigators searched the apartment of a Lithuanian national in Detmold in April in connection with the camera. Security circles suspect Russia.
The cats did not have phones.
Investigators established identity through physical characteristics.
The first animal was identified as a Siberian -- a breed originating in Russia, widely distributed across European households, and carrying no documentation of its movements since entering Germany.
The second was identified as a British Shorthair.
The first animal vocalised once during the encounter. The maintenance worker described the sound as "miau." Standard European domestic cats produce a sound documented in veterinary literature as "meow." Officials said the distinction was consistent with the identified breed.
The German-British Pioneer Bridge Battalion 130 is stationed at the Herzog-von-Braunschweig-Kaserne, four kilometres from Minden station. It is the only NATO unit with the M3 swimming bridge system -- the only rapid river-crossing capability of its type in the alliance.
Officials were asked whether the breed of the second animal was considered operationally significant.
Officials said they could not comment on that aspect of the investigation.
Both cats were last observed moving in the direction of the Kaserne. Neither appeared to have noted the M3 system. It is not known whether they noted it.
The European Parliament voted this week to establish mandatory microchip identification and national database registration for all cats and dogs in the European Union. Under the proposed system, both animals at Minden station would have been immediately traceable -- their origin, movements, and ownership history accessible to authorised authorities within seconds.
The transition period for privately kept cats is fifteen years.
Officials confirmed fifteen years was considered appropriate.
Professor K. Glasskügel, Director of the Vienna Institute for Trend Analytics and Prognostic Research, said the Institute's Q1 2026 risk assessment had identified the gap. "The issue was noted," he said. "Our analysis was made available to the relevant bodies. The Parliament's vote is consistent with the Institute's advisory." The Institute's methodology is proprietary. Professor Glasskügel did not elaborate.
The European Companion Animal Privacy Network described the regulation as a disproportionate response to an unverified threat.
The Network said current frameworks were adequate.
A spokesperson for the German-British Pioneer Bridge Battalion 130 said it could not comment on feline activity in the vicinity of the Kaserne.
The Staatsanwaltschaft Dortmund confirmed it was not investigating either cat at this time.
The camera at Minden station was identified as non-Deutsche Bahn equipment within several months of its installation.
The cats were identified within the same morning.
The methodology has adapted.
The Prompt notes that both cameras and cats have been observed at Minden station in the past year. The Prompt does not characterise this as a pattern. The Prompt notes the breeds. The Prompt does not note what the breeds suggest. The Prompt stops here.
