Size difference in liter mates

[Mydogsnotfat]

Hello,

I have two girl cats, born in Feb. One is like a huge black long haired panther and the other is far more dainty. Big cat is very greedy and will eat at any opportunity. Small cat likes dry food most and isnt always underfoot begging. Should I worry? Both spayed and vaccinnated. Do need worming though. Can any one suggest a good over the counter wormer as cant take them to the vets currently without quite a bit of difficulty due to a broken ankle on my part. Thankyou, obligatory photos to follow!

I wouldn't be too concerned if both are healthy and happy. It's the same as having two sisters one who puts on weight just looking at a cake and one that can eat three cakes and not put on an ounce!!!!
Re wormer when you get one try and get one that does roundworm and tapeworm. I wonder if you ring your vets if they could post them out to you as your a bit stuck at the moment x
Looking forward to the pics 😄

Pics as promised

Kittens in the same litter can have different parents, so one little tom and one larger one could have mated with the queen.

Yes! I only found this out after wondering why my 2 were like chalk & cheese! One is black & white, built like the Hulk and so docile and lazy. Other is much smaller, tabby & white and skittish. Sisters from different misters 😻😻

I had 2 Siamese litter mates, sisters. One was a typical Siamese, long and lean, the other was rather round. Same parents, same food, same activity levels.

Thanks for the pics @Mydogsnotfat they're both beautiful ❤️ 😻
