i woke up this morning and was putting away my christmas decorations under the stair well where our sump pump is. i heard some splashing and swimming i looked in and i saw a big scared frog. he had to have been in there for a month maybe living off some spiders he found. he would not service the whole winter in there so we took him out with a ladle put him in a large container with some water and rocks. now i have no idea what to do with him he looked awfully skinny so i gave him a spider now what? help please!
