Safety, trust & environment

I'm compassionate and trustworthy. I'm a lifelong pet owner and a mom with lots of experience. I will care for your pets with care. I'm happy to set up a regular routine, or provide one-off services. If your pet is friendly with children, I may bring my 9-year-old daughter along to help. She's been caring for pets with me for years, and at home she is responsible for walking and feeding our dogs daily. She's even earned her "Critter Care" loop in the Cub Scouts! If you'd prefer she stay home with her dad, that's definitely fine too! Whatever you are comfortable with.

Information Justina M. would like to know about your pet

Let me know what your animals love to do, and what will make them feel safe, secure and at-ease. Any information to make your pets feel special, safe and happy is helpful!

A typical day

I'm happy to take dogs on long walks or hikes, bring them to the dog park and play fetch in the yard. I can entertain cats with toys and games. If what they need is companionship, I'm happy to just be present in your home. If you like, for animals friendly with children, I can bring along my 9-year-old daughter to play.

Justina looked after our Puggle Daphne and our fish when we were out of town for a few days. She was easy to communicate with and shared lots of pictures. Our pets were happy and healthy when we got back home.

Absolutely wonderful with my small herd of cats, with both the good stuff (e.g. playing with them) and the less food stuff (e.g. giving paste wrapped pill to a mostly-good albeit sometimes-grumpy patient, day and night). Communication is fantastic and I massively appreciate the cooperation with all their personalities, and especially since I had to extend my stay an extra day). I missed my furballs but they were clearly enjoying the interactions, and the shyest even came out of her shell and joined in vs watching from a short distance of halfway up the stairs). Thank you SO much!
