Bout the food, the previous owner told me he feed Simba with IAMS. But I just bought Jojo's Science Plan. So the first nite Simba had Science Plan (my bad), but the next day i quickly change back to IAMS. Till today, Simba is not eating much. Currently im giving only IAMS and he continues sleeping all day long..

Thx for the advise, i will try to make my time to bring Simba to vet asap.
