When summer heat makes midday walks unsafe, enrichment keeps dogs and cats engaged without overheating. The best activities tap natural instincts – sniffing, foraging, licking, chasing, problem-solving. For dogs, this means snuffle mats, puzzle feeders, frozen lick mats, and short training games. For cats: food puzzles, wand play, and climbing or hiding spots. A few ten-minute sessions of mental work can keep a pet settled through a day that’s too hot to walk.
