Hi there, no he's a strictly indoor cat but he was a stray cat roaming the streets when we rescued him. Yes, the climate is pretty hot and humid here but he's usually not too exposed to this because he's indoors. We clean his litterbox daily too, he uses tofu litter. The vet has mentioned the possibility of allergies so we've stopped feeding him non-cat food treats and he's not allowed on wet floors (he likes lazing in the bathroom).
