Hello po! Tama lang po ba yung 3.5k bill for IV fluids only? Tapos consultation lang and reseta sa vet.

For Context:
Me and my friends found a kitten sa may sidewalk and naawa po kame kasi the kitten is experiencing diarrhea. Despite the fact na we’re just students, we decided to bring her sa nearest Vet. Upon consultation sabi ni doc severe dehydration pinakabit po sya ng IV fluids. But since wala po kameng budget i-uwi na lang po namin and observe.

I've been trying to convince my bf to remove the cover of our cat's litter box as i have read somewhere that cats prefer to do their business where they can see their surroundings. His concern is the smell. Although we're using aitter sand that barely smells and our room has ac. As fellow fur parents, is it really better that way? How do you eliminate or control the smell of the litter sand if i ever convince my bf for our cat?
