The Dumb Friends League has a history of service. For more than 100 years, we have sheltered and cared for lost, abandoned and abused pets. 

Thanks to wide community support, we offer programs that help both pets and people. 

We are proud to be the metro-Denver area’s local humane society. You are invited to visit our website and our two shelters to learn more about us.

Aggressive Behavior

Cats under 18 months

Play-motivated aggressive behaviors are common in young, active cats less than two years of age, and in cats that live in one-cat households.

Well-socialized cats are more likely to have well-socialized kittens. Kittens “feed” off of their mothers’ calm or fearful attitude toward people.

Clicker training uses a precise sound (a click) to tell the cat that he has done something to earn a reward. Watch a clicker-trained cat in action!

Improving your relationship with your cat through daily interactions.

While pet owners would never consider withholding food or water from their cats, many forget to provide adequate exercise and stimulation. Yes, cats do sleep a lot, but play is an important component of any pet’s health and well-being. The release of energy triggered by regular daily interactive play sessions can help alleviate stress and prevent behavior problems.

There are many factors that contribute to the safety or danger of a toy. Among them are your cat’s size, activity level and personal preference. Another is the environment in which your cat spends his time. Although we can’t guarantee your cat’s enthusiasm or his safety with any specific toy, we can offer the following guidelines.

An aversive is something that your cat finds unpleasant. It can be used to discourage her from a particular action or place.


Cats over 18 months

Cat owners sometimes have difficulty understanding why their cats, who seem to be friendly and content one minute, may suddenly bite and scratch them the next.

We are able to assist pet owners with many types of problems; however, there are some we can’t resolve by e-mail or phone.

It’s important to have realistic expectations when introducing a new pet to a resident pet. Some cats are more social than other cats.

Cats are territorial and need to be introduced slowly in order to give them time to get used to each other before there is a face-to-face confrontation.

Living with a cat can be beneficial to children. Cats can enhance children’s self-esteem, teach them responsibility and help them to learn empathy.

It’s impossible to estimate how well any particular pair or group of cats will ultimately tolerate each other.

When cats feel threatened, they usually respond in three ways to the object, person or situation they perceive as a threat: fight, flee or freeze.

If you want your cat to live a long and healthy life, keep her inside.

Many people have a problem with roaming cats that attack wild birds as they feed or nest in their yards, that use their garden as a litter box, or that upset their pets by invading their territory.
