Oh no, Jen, not little Rain! That poor sweet little boy. There's major LES going on here right now. Please know that prayers are being prayed and will continue that whatever may be bothering Rain isn't serious and he'll be back to the active, curious, playful kitten your PT friends fell so easily in love with in no time.
When you get the chance, please let us know what your vet has to say?

Hey there Rain, Be a good boy for Meowmie and the whitecoat. They want to find out why you don't feel good and help make you better. Sending tons of love and good vibes your way.
