Hmm CA? You mean cali? Or cane toads? Well here is what I gathered from a friend, go to an expo and buy yourself a ton of weavils, also you could try feeding baby roaches, and small moths.
As for care tips. I think if its a cane toad just mimic a tropical environment. Mine seems to be happy on one. As for a CA toad. Iam guessing foresty?
I think if you have a toad you should stick to plain DIRT, because its good for digging and it doesnt stick to them like coco husk, and not as messy. Make sure to m ake the substrate 4-5inches deep. Get a large pile of leaves and put em on one side, theyd hide under it. Also get those habba huts, they like those for some reason. Make sure you have a dish of water for them. If you have enough room you could get a really small rubbermaid, and use it as a swimming hole for them or a 2 gallontank. Lol. All toads except the sonoran desert toad doesnt like really bright lights. SO make sure, you have a decent dim light. Nothing thats too bright. To them, its like you going to the dentist and them shinning that extremely obnoxious bright light onto you. If its a north american toad, just keep the temps up to 68-72. They dont like extremely warm temps, or extremely cold temps. But they do appreciate "cool-warm" temps Like in between. Not too hot, but not too cold.
I would cover the backside, left side, and right side of the terrarrium with a black background. I suggest the construction paper, since it doesnt "shine" and reflect the shine on to the tank annoying the crud out of the toads.
Favorite foods for toads:
MOTHS
Earthworms
Slugs, snails.
Roaches
Grasshoppers, crickets and locusts.
Beetles(dont give more than 4 per 2-3 weeks or it can cause impaction)
Wax worms.
Pheonix worms(high in calcium)
Iam sure theres a few insects I havent mentioned, but thats the most varied diet for an adult.
Dont feed:
Mealworms
Fireflies(toxic to all animals)
Goldfish(high in fat and transmits parasites and illness).
I cant think of anymore.
Just make the tank elaborate, and change the furniture around every month to keep the toads interested.
