My 5-week-old kitten is lethargic, throwing up, and can't walk well.
Kittens are susceptible to many different infections, both viral & bacterial. A heavy parasite burden from coccidia, or roundworms can also wear a kitten down & leave it weak. Pascal is too young & small to try & fight this off on his own. He needs to be seen by a veterinarian as soon as possible. If you can not have him seen tonight or tomorrow, pick up some Nutrical from Petco tomorrow, & try to give him small amount frequently throughout the day. This is a high calorie supplement to hopefully keep his energy up. Then please try to have him seen by your veterinarian as early as possible on Monday. I hope he does better soon. Thank you for using Petco Pet Education Center, formerly Petcoach.
