The agency said the Stockholm woman told authorities she had a contact with the owners of a tomcat named Ove to have the male feline mate with her own pet, which she said is in heat and will urinate on the walls if a mate is not found in a timely fashion, Swedish news agency TT reported Wednesday.
The woman said Ove's owners were attempting to back out of the deal.
"It's not so unusual for us to make these kinds of decisions," Caroline Riderstal, the Enforcement Agency supervisor for the case, told The Local.se.
"We came to a decision on a contract basis and such instances crop up from time to time -- it can be about anything at all. If something needs to be moved, then it can be something we work with. The owner wants action and that's why she left the case in to us," Riderstal said.
Riderstal said the agency has ensured Ove's owners will allow him to breed with the woman's cat.
