Jean we started out with dry food and that is all they have known, Whiskas brand, and we had them declawed so they have never been outside - other than one time the older cat got out and was gone for 2 days - we were sick as we have lagoon in back yard with alligators - someone told us to put the litter box by the back door and sure enough at 3 am I heard her crying - Tony never liked cats - he adores these two cats!!! Ours share a litter box - no problem - neither one of ours will just jump into our lap so you are lucky!!! We also put some flea medicine on them once a month, little vial of some liquid, and have never had any problems with fleas!!
