LA CROSSE, Wis. -- If you're a pet owner, you probably got a letter in your mailbox earlier this week reminding you to get your dog or cat re-licensed.

All dogs older than five months have to be licensed and tagged every year sometime between Jan.1 and April 1.

As far as whether your cat needs a license, it depends on where you live. In the city of La Crosse, both cats and dogs have to be licensed.

To purchase a license, you must have proof of a current rabies vaccination, and proof of whether your pet is spayed or neutered.

Executive Director of the Coulee Region Humane Society Heather Schmid says the tags help lost pets get back to their owners quickly and safely.

"We see so many stray pets come into our facility. And when they have that license tag, usually we've got that pet home within a day-- if not less time. And knowing that we only have about seven percent of our cats redeemed that are lost-- stray cats-- it's super important to get that tag on a cat especially," said Schmid.

The tag fee varies by city, so make sure you check with your city treasurer to find out how much it costs in your area.

In the city of La Crosse, a license for a spayed or neutered pet will cost you $11. A license for a pet that is not spayed or neutered costs $21.

If you do not pay your license fee by April 1, you'll have to pay a $25 penalty per animal in addition to the cost of the tag.
