my vet told us that 4kg was averege healthy weight my molly is 5kg.5 and the vet said she was very overweight "[i nuked the end of this quote, now it's showing as one long quote....sorry, no PC skills]The specialist vet clinic told me to try not to let a cat get over 5kgs by too much as it places an extra strain on his heart & is more dangerous if he stops eating. Depends also on the size of the cat. 4kg would be too little for a big boned cat. The least my burmese Swamp's ever weighed as a healthy adult is about 4.5kgs. Before he got ill in Oct he weighed too much - about 5.2kgs (french food lol). One week in hospital on a drip and he went down to 4.4kgs - so depends on the cat. I was told it's important to give the same amount of food to keep weight stable.When they were younger, they went on a diet (Hills Diet food) for 3 months and lost weight very gradually. It's dangerous to be too porky but also to lose weight too fast.As for giving pills, a fool proof method (er, in theory) is to catch Kitty when s/he is fast asleep, open mouth and drop it down FAST! I've never had a cat that would touch food with a tab hidden in it. That's for dogs, da enemy
