Rescue kitten help
Yesterday me and my grandma rescued this little guy from an elderly couple out in the sticks. I think he's about 4 weeks old at this point and he was COVERED in fleas. I've never cared for a kitten this little and everything is making me incredibly nervous. I feed him a mix of wet food and KMR and he eats a few times a day and mostly sleeps. The couple said they hadn't seen him poop and last night he finally did. All over himself and the crate.
He hasn't pooped today even though I've being trying to stimulate him. He's pretty good about eating in his own. I give him a platter of the wet food mixture and he nibbles on it throughout the day. I'm just anxious because I leave for an out of state day trip tomorrow and won't be back until early evening. My mom said to put him in the tub with the litter box and food and water but I'm worried he'll get too cold even with his blankets and stuffed animal. We have a vet appointment scheduled for Tuesday, but I want to make sure he's getting the best care he needs.
Edit: Good news!! My friend is able to come over and stay with him all day tomorrow! I've given her his food routine and how to stimulate him to use the bathroom after eating. Thank you to all the help in the comments, I needed the support to make sure I can take care of little Percy to the best of my capabilities☺️
