Answer: Based on the information provided, It does sound like a ringworm infection, but I never read anything about a ring-shaped rash or any raising on the foot. It more or less sounds like a mixture of both Ringworm, Toe Fungal, and Atropic Dermatitis. In my opinion I would classify it as a Ringworm Infection only if the child had direct contact with his/her feet after making contact with the cat. it's more of a 50/50 on how the child contracted this medical issue because, as I've read, It could be both Ringworm and Atropic Dermatitis. I can't exactly say it's Ringworm though due to nothing being mentioned about a Ring-shaped rash or and swelling/raising of the rash site.
