I have a 6 month spayed female and a 4 month old male unneutered (to be done in the near future). They were introduced beginning of February, there was an adjustment period and were doing well. The past few days, my girl doesn't seem to want much to do with him. She has been sleeping a lot, but eating and pooping fine. I was concerned there was something else, but last night she came up to bed with me and had her normal playful behaviour with me, purring etc. Is it just teenage behaviour? Tired of all the little guys antics? She gets angry with him if he plays to hard, but lets him lie by her and groom her. They were playing a lot together before. She would still chase balls etc. Still not sure what's going on. She has all her shots, has tested negative for feline leukaemia. She had injured her leg as a kitten - so I wondered if it had been bothering her. I gave her some meds last night (with the vet's approval) to see if there was any difference. I'm not sure but she did play with me about 4 hours later. Any thoughts?
