We have a new rescue cat. She’s about 13 as far as we know and was at a vet practice for a month having been found as a stray, with a large dental abscess and ticks. She’s had the all clear medically but is still very skinny. She’s been treated for worms and fleas. Been with us for two days and now she’s settling in she’s asking for food all the time. What sort of feeding regime would be best for her. Was thinking three smallish meals a day. Any advice very welcome.
