I got a kitten a day ago, and the lady that gave the kitten to us said that she found it on the side of the road, and had already put Frontline on it that day. It was fine the first day and very playful, but the second day it was very lethargic and is vomting something that looks like white spit. The gums are pinkish white and its dehydrated. It also will walk to its water and then just sit there like it wants to drink but wont. It ate a little, and is still using the litterbox. I think it has to do with the Frontline, because the kitten can't be more than 7-9 weeks old. I gave it some milk and powder milk, but it wont drink that either. I also tried to play with it, and it tried to play but quickly stopped. Thank you for your help.
There could be many reasons why your pet is not feeling well. It is possible that the frontline is causing a problem. I recommend a vet vsiit asap. vetcare
