Last night our European female had two kittens (on the 68th day of pregnancy). She is approximately three years and had a litter last fall.

The three kittens from this litter are well and have developed into nice Europeans. However, the result from the night’s birth was less successful. The first child was dead and the child who arrived four hours later had severely deformed hind legs.

They were backwards, curled up and completely stiff. In the first born kitten I could not see any malformations. The litter consisted of two kittens.

My questions are:

1. Are malformations usually caused by infections or are they usually genetically determined?

2. If it is the case that the malformation is probably due to a genetic inheritance, should I take my female out of breeding?

3. The three kittens she got in the last litter (her first litter) should they also be taken out of breeding?

4. Should you also avoid mating on my female littermates?
