This weight business is something that bothers me... it's clear reading through various threads that weights for similar ages can be wildly different - Larry and Monty and JCKKerrison's litter mates are two great examples of that - but Freyja seems much lighter that some of the kitties at 6 months. She gets two wet pouches/ tins a day - Applaws in the morning and Cat Deli in the evening, both at least 50% meat. And she's got biscuits down all day to graze on - it's been RC Kitten 36 until the last 2 weeks, when we changed to Go Cat Complete Adult and Meowing Heads.
She usually polishes off her pouches - just a few crumbs left - and rarely finishes off the biscuits. Sometimes she wines for more food when she's still got biscuits down, and if her wet food has gone I will put down a small block of coley fish, which she usually wolfs about half down. I've noticed in the last couple of weeks that her appetite seems to have increased, and I'm guessing that might be as a result of her being spayed?
She was weighed the day she was spayed and was 3.4kg, and yesterday I weighed her (yes, finally worked out the best way to do it!) and she was 3.8kg. The day I brought her home (3.5 months ago) she weighed 1.5kg.
Howlinbob, would be interesting to know what the boys weigh now as they're almost exactly the same age as Freyja.
My worry is that I'm under feeding her, although - as I mentioned above - she rarely finishes her biscuits off, and I would think if she was THAT hungry she would tuck into them.
