Query: Not enough charge

My cats liked it but the stupid thing, after charged, only holds 30 seconds to a minute of the charge, only works on hard surfaces, the wheels get stuck,it only goes in reverse for 5 seconds and turning doesn't work after the next second.Why can't someone make one that lasts longer like the toy cars?This isn't worth it. Save yourself time, batteries and money and attach a mouse to a string.Maybe I will just buy a remote controlled car. My cats won't know the difference.
