I've found a cat in Longueuil

  • Call Proanima at 450-655-2525: it handles animals for the City.
  • No tag doesn't mean no owner: in Longueuil, cats don't have to wear their tag.
  • Their microchip, if they have one, is read with a device that vets and shelters have.
  • A cat outdoors isn't necessarily lost: how to tell.

Getting your cat back

At the pound, the City asks you to pay the fees set by its bylaw and to prove you have a valid licence for your cat. The holding period is 3 business days for a cat with a City licence, and 1 business day if their owner can't be traced.

The rules in Longueuil

  • Licence required for cats, valid January 1 to December 31 and renewed every year: $5 for a sterilized cat, $10 otherwise. It's still required for a cat who never goes out or who is microchipped. Buy it at licences.proanima.com/longueuil.
  • The tag is given at the first registration, then a sticker in a different colour every year. Lost tag: $3. A cat doesn't have to wear it.

Street cats

Proanima has a community cat program (TNR, called CSRM in French): registered colony caretakers, free sterilization for the colony's cats, a trap lent for 7 days against a deposit. Cats are marked with a notch in the left ear and a small green tattoo. The program covers Proanima's "partner cities" without naming them: check with Proanima, at 450-655-2525.
