The Baltimore Humane Society is continuously looking for caring and devoted individuals to provide foster homes for animals in need. To increase these animals’ chances of adoption, they must be placed into foster care where they can receive the one-on-one attention that they need. Our need for foster homes is especially great during the spring/summer kitten season.

Some of our animals need to heal, mature or calm down a little before they can be adopted out. They may be too young, too sick, or not socialized enough. Some just do not adapt to shelter life or have been here for a long time and need to move to a home environment.

Would you like to help them get back on their paws? Give a stressed, homeless animal a chance to decompress, remember what it’s like to be in a loving home, and brush up on its training so it is able to be adopted.


Sir Roc

Currently in foster but they are no longer able to continue fostering. He is gentle and loves people. He loves to play with balls and toys and enjoys car rides. Enjoys going for walks and napping. He lives with a cat and kids in his foster home. He does not tolerate being at the shelter well without becoming very stressed out. Click for pet info


My name is Mercedes and I'm a two-year-old DSH. It takes me awhile to warm up to people, but with time, patience and understanding, I do. I am looking for a quieter home where I can chill and slowly come out of my shell. I'm really curious and interested in what goes on around me, but I'm a bit of a nervous Nelly. I have an independent spirit and would benefit from being with an experienced cat guardian in a place of my own. Click for pet info


He loves people and runs around with a big smile always on his face. He doesn't have the best manners yet and sometimes forgets how big he is but overall he is just a big goofy boy! He is starting to show signs of stress from being at the shelter for a while. Click for pet info


Hi! My name is Sunny and I'm an eight-year-old DSH with diluted tortie markings. I'm an inquisitive little lady and who enjoys hanging out in my cat tree in front of the window so I can watch all the critters. I also love when someone plays with my wand toy with me so I can show off my acrobatic skills as I try to catch it! I am not too into being touchy-feely but I like to be with people and enjoy taking short cat naps on laps! Seeking experienced cat guardian to foster/adopt. Click for pet info

Foster Opportunities

Fostering is a great way to help a shelter pet in need. Our shelter staff identifies the best candidates for foster based on behavior and medical needs. When you commit to fostering a shelter pet, you commit to getting them adopted. Part of that commitment means providing BHS with photos and videos of your foster for promotional use. We hope your fosters will wiggle their way into your hearts and start to feel like a visiting family member.

General Foster

A general foster does not need any specific training, just patience, love, and a couch to snooze on.

General fosters most likely care for:

  • Senior shelter dogs and cats
  • Long term residents
  • Any pet in need of a break from the shelter

Kitten Foster

These fosters are utilized the most April-July during Kitten Season. They care for kittens under 8 weeks of age and return them to the shelter for spay/neuter and placement for adoption at 8 weeks of age.

Care focuses on nutrition, socialization, any necessary medication administration, and maintenance of a confined, clean, and safe space for the kittens, away from other animals. Many of our fosters utilize a small bathroom for this purpose.

Types of care include:
• Mother Cat and its litter of kittens 0-8weeks of age- requiring the least amount of care, ensuring adequate nutrition and socialization (usually 1-6 kittens)
• Orphaned Bottle Baby Kittens 0-4 weeks of age- requiring the most amount of care, bottle feeding every 2-4 hours (2 kittens at most)
• Orphaned Kittens 4-5 weeks of age transitioning over to solid food, eating gruel with some assistance 4 times a day (usually 1-6 kittens)
• Orphaned Kittens 6-8 weeks of age eating regular canned and dry kitten food on their own 3 times a day (usually 1-6 kittens)

Kitten fosters must be able to bring the kittens back to the shelter for veterinary exams and vaccinations every 2 weeks M-F 9 am- 4 pm.

Behavior Foster

A behavior foster is someone who has experience with positive reinforcement training, is comfortable handling large dogs, and able to follow any and all training protocols given to them by the shelter.

Typically, most behavior dogs need a foster that does not have other pets or small children.

Cat behavior fosters need to be able to recognize the signs that a cat is overstimulated or afraid and how to respond appropriately. Must be able to follow all training protocols given to them by the shelter.

Medical Foster

A medical foster is someone comfortable administering oral and/or topical medication.

Medical fosters should be comfortable changing bandages and must have a schedule that allows them to bring the foster pet to BHS a few times a week, depending on the situation.

Medical fosters must be able to follow and adhere to all care directions given by our vet.

Frequently Asked Questions

Animals that require a foster home have specific needs and requirements. We must ensure that the animals in need of fostering get priority. Based on your application you will be matched with the best fit!

  • Follow all instructions given by BHS shelter staff.
  • Bring foster to all vet appointments.
  • Bring foster to shelter to meet potential adopters.
  • Email 3-5 photos of your foster to weekly.
  • Refer anyone interested in adopting your foster to our adoption counselor to learn more about the adoption process and to see if they are a good fit!

It can vary depending on the shelter pet and their needs. Typically, general and behavioral fosters are checked by our vet two weeks after they leave the shelter, a month after their first visit, and three months after their second visit if they are still in foster care. Your foster may get sick or injured while in your care, which may require additional visits. You MUST be available to take your foster to our BHS vet during the traditional work week.

All appointments must occur Monday-Friday 8am-4pm. We do not have vet hours outside of scheduled hours.

Eventually! We require at least a two-week shutdown period where your foster does not interact with other pets. Different circumstances may require a longer separation or that your pets never meet—which is the case with kittens and pets with certain medical conditions.

We provide food, harness, leash, enrichment toys, and a personalized plan. We can provide our cat fosters with litter boxes, cat litter, and carrier. We offer crates for dogs if necessary.
