Hi, so recently we applied the anti flea treatment and my cat accidentally licked it, since then problems began to arise at first he was very dull and wouldn't eat then after 2 days he's fine , he starts to play around like he usually does. However , he has stopped eating his dry and wet food. He only licks it then goes away. The wet food brand we use (whiskas) he goes absolutely crazy when he sees it but now he doesn't. He only eats dry food if its out of my hand, and he doesn't drink much water either, I don't know what to do, I'm still debating if I should take him to the vet or let it fix by itself.
