I have a pet mouse about a year old. He was very active but from last few days he has stopped eating or drinking anything. He even does not walk properly. He hardly moves his hindlegs and drags them along his body as if the legs are dead. Please help me with what should i do to make him walk properly. I gave him an antibiotic named terramycin and he has started eating and drinking to some extent. Please note that the weather here in India is very hot and humid these days (about 45 degrees celcius) but I have ensured that my pet stays in a colder environment. His bedding is fine - a cage with a plastic base and ventilated sides.
