🏫 Which classroom pet is right for your class?
Answer 11 questions about your room, your students and your school calendar. We rank 22 classroom pets on what decides a class pet in real life: who covers weekends, whether anyone has allergies, what your school allows and what happens over summer. Every result comes with a weekend plan, student jobs for your grade and a setup list. It takes about two minutes, and every question is listed below before you start.
We use this for safety rules and to pick student jobs your class can do.
Classroom advice on this page is reviewed by Stacey Fernandez, M.A., a K–8 teacher. Care facts follow the veterinary and welfare sources on each pet's page.
The 11 questions, and how each answer counts
Here is every question in the quiz, with its answers and exactly what each one does to the ranking. Skip any question you can't answer yet: the quiz leaves that rule out, so you can come back to the school-policy or grant questions once you know.
What grade do you teach?
We use this for safety rules and to pick student jobs your class can do.
- Pre-K (under 5)
- Kindergarten to 2nd grade
- 3rd to 5th grade
- 6th to 8th grade
- 9th to 12th grade
- A mixed-age group or homeschool co-op
How this answer counts: Pre-K removes reptiles, amphibians and rodents, quoting the CDC: "Reptiles, amphibians, poultry, rodents, and ferrets aren't suitable for settings with children under 5 years old." Grade also sets which student jobs appear (from each chore's youngest age) and removes pets whose youngest grade is higher. A mixed-age group or homeschool co-op adds a note to the Pets in the Classroom answer in question 10, because homeschools don't qualify.
Does anyone in your class have animal allergies or asthma?
Ask your school nurse if you're not sure. Asthma rules out more pets than any other answer.
- No
- Yes
- I need to check
How this answer counts: "Yes" or "I need to check" removes pets with fur, feathers, hay, bedding dust or cockroach allergen. "I need to check" also shows a banner to ask the school nurse before buying.
What does your school or district allow? Choose all that apply.
Many districts have a written animal policy. If you haven't seen yours, choose the last option and we'll flag it.
- Any classroom pet
- No reptiles or amphibians
- No mammals
- No insects or spiders
- No heat lamps or plug-in heaters
- I haven't checked yet
How this answer counts: Removes the groups your school bans. "No heat lamps or plug-in heaters" removes pets that need a basking lamp or a heat mat. "I haven't checked yet" adds a check-your-policy banner that links the toolkit checklist. An optional state picker removes pets that are illegal or restricted in your state.
Who checks on the pet over a normal weekend?
Think of a typical Friday, not the best case.
- Nobody. It's on its own from Friday afternoon to Monday morning.
- I can come in once.
- It goes home with me or a student's family.
How this answer counts: Uses the weekend chores in the care plan. "Nobody" removes every pet with a chore that can't wait until Monday. "I can come in once" covers pets with at most 2 weekend chores, so guinea pigs and rabbits stay out. "It goes home" covers any pet, and ranks small, light enclosures higher, because weekly travel is hard on most animals.
What happens to your room's heating or air conditioning at night, on weekends and over breaks?
Many schools turn the heat down to save energy. Your custodian will know.
- It stays about the same
- It turns down or off
- I'm not sure
How this answer counts: "Turns down or off" or "not sure" flags every pet that needs warmth with "needs heat on a thermostat" and moves its heater and thermostat to the top of the setup list. "Turns down or off" also removes cool-water pets such as newts, because a room without air conditioning can get too warm for them.
How should students interact with the pet?
- Watch and observe
- Gentle, supervised holding
- Hands-on care and handling every day
How this answer counts: Scored against each pet's handling rating. "Watch" never removes a pet you can hold. "Hands-on" ranks look-only pets lower.
What's the main reason you want a class pet?
- Class jobs and responsibility
- Life cycles
- Habitats and ecosystems
- A calm corner to watch
- A class buddy students bond with
How this answer counts: Boosts pets with that lesson hook, for example stick insects and mantises for life cycles, isopods and shrimp tanks for ecosystems, guinea pigs and rats for a class buddy.
Where will the pet live?
Keep it away from windows, heaters, vents and the door. Sun through glass can overheat a tank in minutes.
- A counter spot about 2 feet wide
- A table about 3 to 4 feet wide
- A corner of the room
How this answer counts: Removes pets whose minimum enclosure won't fit, using the space column of the table.
What can you spend on the setup?
Just the one-time setup. Monthly costs are on each result.
- Under $50
- $50 to $150
- $150 to $300
- More than $300
How this answer counts: Compared with the low end of each pet's setup cost from the pet cost study. Over budget becomes "Works with a plan", not a removal.
Are you applying for a classroom pet grant?
Pets in the Classroom gives Pre-K–12 teachers in the US, Puerto Rico and Canada one initial grant per lifetime.
- Yes, Pets in the Classroom
- Other funding (PTA, DonorsChoose, a local business)
- No
How this answer counts: Pets in the Classroom limits results to grant-eligible animals (insects are excluded) and adds the matching grant note to each result. Pets the terms don't name get "ask the Trust".
What happens over summer break?
- I'll take it home
- A student's family will foster it
- It has to stay at school
- It's a one-term project
How this answer counts: "It has to stay at school" shows a plain note that no pet can stay alone all summer, and ranks pets that travel easily higher. "One-term project" ranks short-lived invertebrates higher. Every result shows the lifespan.
How the 22 classroom pets compare
These are the facts the quiz scores. Weekend chores come from each pet's care plan: a chore that can't wait until Monday means someone has to come in or take the pet home. Grant means the Pets in the Classroom 2026–27 terms.
| Pet | Weekend chores | Allergens | Awake | Space | Youngest grade | Grant |
|---|---|---|---|---|---|---|
| Betta fish | None | None | Awake in class | Counter, about 2 ft | Pre-K | Yes |
| Community fish tank | None | None | Awake in class | Table, 3–4 ft | Pre-K | Yes |
| Shrimp and snail tank | None | None | Awake in class | Counter, about 2 ft | Pre-K | Probably |
| Land snail | None | None | Asleep during class | Counter, about 2 ft | Pre-K | Ask the Trust |
| Crayfish | None | None | Asleep during class | Counter, about 2 ft | Pre-K | Probably |
| Newt | None | None | Dawn and dusk | Table, 3–4 ft | K | Yes |
| Aquatic frog | None | None | Asleep during class | Counter, about 2 ft | K | Yes |
| Guinea pig | 5 | fur, hay, bedding dust | Dawn and dusk | A corner | K | Yes |
| Pet rats | 1 | fur, bedding dust | Dawn and dusk | Table, 3–4 ft | K | Yes |

| Hermit crabs | None | None | Asleep during class | Table, 3–4 ft | Pre-K | Yes |
| Stick insects | None | None | Asleep during class | Counter, about 2 ft | Pre-K | No |
| Praying mantis | None | None | Awake in class | Counter, about 2 ft | Pre-K | No |
| Hissing cockroaches | None | cockroach allergen | Asleep during class | Counter, about 2 ft | Pre-K | No |
| Isopods | None | None | Asleep during class | Counter, about 2 ft | Pre-K | Ask the Trust |
| Ant colony | None | None | Awake in class | Counter, about 2 ft | Pre-K | No |

| Tarantula | None | None | Asleep during class | Counter, about 2 ft | Grade 6 | Probably |
| Jumping spider | None | None | Awake in class | Counter, about 2 ft | Grade 3 | Probably |
Some of them are restricted in parts of the US and Canada. Check where newt, aquatic frog, gerbils, leopard gecko, bearded dragon, corn snake, hamster, aquatic turtle and axolotl are legal before you buy.
Popular pets the quiz explains instead
Teachers ask about these often, so the quiz names them with the reason they usually don't work in a classroom.
- Hamster: asleep during class, and likely to nip when students wake it.
- Rabbit: needs pen-sized space, unlimited hay and 5 chores that can't skip a weekend.
- Aquatic turtle: salmonella risk (why US shops can't sell turtles under 4 inches), a 20–40 year life, and one of the biggest setups.
- Axolotl: needs cold water, and a warm classroom or a summer heat wave is dangerous for it.
- Chinchilla: overheats in warm rooms, needs daily out-of-cage time, and is awake at night.
- Parakeet: feather dust affects allergies and asthma, and it needs a flock buddy and daily time out of the cage.
Questions teachers ask
What is the best classroom pet?
For most classrooms, a betta fish or a small community fish tank. Neither has allergens or weekend chores, and both fit on a counter or table. If your class wants to hold a pet and someone can cover weekends, guinea pigs and rats are the most hands-on choices. The quiz ranks all 22 for your room.
What classroom pet can be left alone over the weekend?
Fish, betta fish, leopard geckos, corn snakes, hermit crabs, stick insects, isopods and most other invertebrates on our list have no chores that can't wait until Monday. Guinea pigs and rabbits need someone every day.
What is a good class pet for students with allergies?
Choose a pet with no fur, feathers or hay, such as fish, a leopard gecko, isopods, stick insects or hermit crabs. Skip hissing cockroaches if anyone has asthma, because cockroaches are a common asthma trigger.
What pets should a preschool classroom avoid?
The CDC says reptiles, amphibians, poultry, rodents and ferrets aren't suitable for settings with children under 5. For Pre-K that rules out guinea pigs, hamsters, geckos and frogs. Fish and many invertebrates remain.
Can I use a grant to buy a classroom pet?
Yes. Pets in the Classroom gives Pre-K–12 teachers in the US, Puerto Rico and Canada one initial grant: a store coupon, or a rebate of up to $125 for an aquarium, reptile or amphibian, or up to $75 for a small animal, bird, hermit crab or betta. Insects aren't covered, and applications close April 30, 2027.
Who takes care of a classroom pet over summer?
No pet can stay alone at school all summer. Most teachers take the pet home or line up a student's family to foster it. Pets in small, light enclosures, such as insects, isopods or a land snail, travel most easily.
