Introducing your Jack Russell Terrier to Cats

So, you think your Jack Russell is lonely and wants a companion. Having a buddy for your dog to play with while you’re at work is an admirable idea and a good one, if you think he is willing to share his living space and belongings with the other pet and if you have the finances and the option to include a new pet to the home.

The trick with a cat and a Jack Russell Terrier is that they take a lot of time to get used to each other and this must be taken seriously, otherwise harm and damage can be done to both the dog and the cat. If this is something you’re dedicated to doing, keep reading for all of the information to make this transition easier for you and your furry family.

What I found helped my dog a lot for being calmer when stressful situations are about to occur are L-Tryptophan dog supplements, they are completely natural and with my experience do work, give them a try.

Would your Jack Russell love to have a companion?

First of all, know your dog well. Make sure he is looking for a companion, and simply isn’t restless or need more attention from you. Some terriers may act lonely, only to lose all signs of that as soon as you try to spend more time with him. So, make sure the situation you’re in is, in actuality, the situation that you’re in. This will make sure that everyone is happy and in the right home!

Second, usually do not get along well with other smaller house animals. This is because they are primarily a hunting breed that are designed to kill anything smaller that is invading its territory. So, a cat may not be the best option.

If you have both the Jack Russell and the cat from babies, this is better than bringing two adults (or one baby, one adult) together, but still not a guarantee that everyone will get along well for the entirety of time together. As mentioned, Jack Russell Terriers can be aggressive toward smaller animals by nature, so the relationship between him and a cat or other animal needs to be carefully monitored and watched.

If you are determined to have both a cat and a dog, make sure that you consult a professional and have him or her help you with interactions and long term monitoring. It may seem like a big investment of money, but it will benefit both animals in the long term and save their lives. It’s something to be taken very seriously.

Welcoming a new pet

Before getting to know each other make sure that both dog and cat are in ideal condition to take care of themselves, not fearful or hesitant under normal circumstances. Essentially, make sure that both cat and dog are a good match personality wise.

When introducing, move slowly and watch for signs of regression or serious fear. For the first couple days, keep your animals in separate rooms and alternate between who is free and who is locked up so that they both can adjust to the home and the new scent that is in it. It’s important not to move too fast, or the relationship will suffer. Once both animals seem to be acting and eating normally, you can move onto the next stage.

This next stage is to allow both dog and cat to see each other. Both should be restrained by person or a leash/cage. Or use a puppy gate to separate them but allow them to see each other and adjust to connecting the scent to the sight in front of them. Take a lot of extra jummy treats for your dog and sit beside the puppy gate and treat him for every curious but peaceful movement. Make this experience positive for both animals.

If your Jack Russell barks, or your cat hisses, close the door/end the contact and allow both to recover and go back to their normal routines. This step will take several days or longer to complete. You must continue doing this one until both dog and cat can see each other without reacting aggressively or without fear.

Getting them to know each ether

The stage after this one is to allow them time to explore each other with their nose. Always move to the next step with both animals leashed. Watch closely their body language, treat them generously for a good behavior and be prepared for signs of lunging from either animal. Make sure you always have another person there to help you in case things get nasty and they start to scrap.

Eventually, you dog and cat will be able to be around each other without a leash or restriction, but it will take a while to get to that point. Never push them into the interaction, let them move in their own pace.

When it comes to living together, make sure that the interactions between cat and dog are always supervised. When you leave the room, take one animal with you to ensure that one does not attack the other while you are gone. It’s like a child, never leave them alone. Disaster can strike very quickly.

When you leave the house, always keep one or both of them barred in a cage or a room. They should never, ever be left to roam the house freely together without you around.

Ensure a secure place for each pet

Make sure there are plenty of high, safe spaces for your cat to jump to in case of necessity or desire to escape from the Jack Russell, and other way around – your Jack should have his own place (a crate is the best) to have his peace if he wants to get away from the cat. It’s important in keeping everyone safe and happy.

This will help you have happy and healthy pets so that your animals can have a companion and be safe about it. If the introduction process is done right, the behavior problems/aggression should be minimal, or perhaps non-existent if you are lucky. Take the introduction between animals slowly and carefully to ensure a good bond forms between cat and dog. You will have positive results and they may even become friends, if done exceptionally well.

Both your Jack Russell Terrier and your cat are important to you. We get that, and want to make sure that everyone is healthy, happy, and out of danger. That’s why this introduction process is so long term and complicated. You have to make sure that both animals are content and feel safe in their own/new homes, and the best way to do that is by involving a professional and always having someone there to help you in case of emergency.

These steps will get you started to having a bigger fur family and all of the blessings that come with it. Be sure to read my Jack Russell breed info in our article the learn more about them.

  1. I need to make up my mind about giving a yes or a no to a dear friend who is offering me a female JR…
    I’d say YES in a flash, but I have three cats and an older female dog.
    I am scared I might go crazy afterwards.
    What are the chances things will work out fine and they will all adapt?

    • Hi Gabriela, I totally understand why you would immediately say yes and on the other hand, I understand why you worry you’ll go crazy. JRT can be really difficult sometimes, but they can also be the greatest dogs ever. In lots of places, I read that JRT’s shouldn’t be mixed with other animals, yet there is a number of success stories where JRT lived happily ever after with cats, dogs, and other animals.
      Before you decide, take into account personalities of your older dog and cats. Would they tolerate small Jack Russell Terror? JRTs tend to be really active, so think if that fits into your way of living, will you be able to give her everything she needs (lots of playing and running, socialization, obedience training…). It’s not easy to answer your question, so make a list of positive and negative sides and weight it all out.
      HOpe this helped a bit. Cheers, Ana

  2. I have a shorthaired Jack Russell that does not bark, does not dig holes, does not act crazy around people. My Jack Russell is like a normal dog. My question was all of this is, is this normal. I had a previous Jack Russell that is since past, that was all of the above. And insanely crazy dog, but was so much fun. Don’t get me wrong, this dog is a lot of fun. It’s just not what I was expecting when I got her .

    • Hi Gilbert, if I were you I wouldn’t worry a bit. Not all JRTs are crazy heads. Some of them are just like normal polite dogs, some are active and some are more relaxed. If she’s healthy, acting normal and fun, you can just be more than happy, it’s like you hit the JRT jackpot :) Cheers, Ana
