Spotty kitten is a chubster, she's 10 months old, has free access to outdoors and free acess to food (good quality dry kitten biscuits). She's an oriental and neutered, her mother is also a chubster and both have got significantly fatter since being sterilized although her mother was 5 when sterilized and spotty kitten 6 months.
Old cat (10, also a neutered oriental) was very depressed after the death of her lifelong partner and got too thin. Spotty kitten has been her saviour and she's enjoying life now and is back up to a good weight. She's been on the kitten biscuits too but I gather she really shouldn't have them. She and old dead cat have always had free acess to biscuits and maintained 'perfect' weight that way. TBH I'm loath to go over to weighed, timed feeding if I can avoid it at all.
So, all things considered, would it be right to move over to adult biscuits this two months early? Spotty cat is, presumably, going to be getting out and about more as the weather improves but I worry that's not going to be enough to sort her weight out and I'd hate for her to drift into obesity.
