My cat "pees" this liquid but I don't think it's actually pee it doesn't smell either. What could this be?

As you likely know, cats normally have very concentrated urine which has a very strong smell to it. If Tommy's urine does not have an odor to it, it might be because his urine is no longer as concentrated as normal. (Urine can actually look and smell like water if it is not concentrated.) I would strongly recommend having your veterinarian check Tommy's urine to make sure that it is normal. It might be a sign of something more going on internally, so your veterinarian may also recommend some bloodwork. I hope that helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

    Hi! Thanks for using Petco Pet Education Center, formerly Petcoach! This is most likely urine. Some cat's urine can be very dilute and not necessarily smell much. Have him evaluated by your veterinarian when he is due for a visit so that he can be examined. If it is truly dilute urine, it would be good to check some labwork to see why his urine is dilute. Good luck!
